Deplean "normally" will not try to remove portage, because it satisfies the virtual/package-manager requirement, which is in @system. If, however, you have portage and another package satisfying virtual/package-manager installed, and the other package was in your world file, but portage wasn't then depclean *would* remove portage. This is the recent behavior change, which is why some people were surprised suddenly when nano or less or insert_your_favorite_virtual_here was suddenly wanting to get unmerged by --depclean.

I've not seen anyone on this list suggest switching to unstable as to fix a bug, though admittedly I don't follow all threads and even the ones I do follow I don't follow fully usually as the signal/noise ratio gets pretty bad over time. But anyway, this isn't even a bug, just a change of behavior. Where were you expecting this "announcement". There usually aren't announcements on gentoo-user. However, it is stated in the ChangeLog (which is where you should alwaysb check first ;-). Also, there was a change to how portage handles virtuals, which was also discussed some weeks ago. But it may not have been done in stable then. They also removed flex, bison, and other things from the system profile. This has broken a few ebuilds (I think I created at least 3 bugs myself). Again, there wasn't an "announcement" AFAIK, you just have to check the ChangeLogs and bugzilla. Anyway I don't think they "announce" every change they make to portage, but they do seem to appear in the ChangeLogs. -a

That and the fact that I had just gotten out of bed when I read it :P They OP could have simply said "Hey, when I synced I saw a message that I there was a new portage available, but when I run 'emerge -up world' or 'emerge -up system' it doesn't show the updated package."

Firstly, regarding the subject line. Portage isn't in world. It's in
the system set.
Secondly, I really don't understand the question. You are in
x86/stable, ok I understand that... Even in stable software gets
updated. Portage is a piece of software. There is an update. There's
nothing "unusual" about that.
What exactly is the question?
You could choose to not upgrade portage (though I don't know why you
would do that), but that would mean you won't receive any bug fixes it
may have, or take advantage of any new features it introduces. Or
things may simply not work :D
What exactly are you afraid of? How long have you been using Gentoo
that you've never had to upgrade portage before?
Or perhaps I'm just not understanding the problem.

There is always (well usually)* an initial /dev created in root. This is needed for before udev kicks in. You should always copy that (and make sure it's /dev on the root fs, not the udev /dev that gets mounted over it. * This was the cause of a bug in the stage3 tarballs a few weeks back, where some /dev entries did not exist in the tarball and the result was that people were able to successfully install Gentoo, but were not able to successfully boot into the installation.

The point was that not filing a bug because you don't know what the problem is is akin having the check engine light on your car go on but not taking it in to service because you don't know why the check engine light is on. As far as diagnostics. You can provide additional information, if they ask you and tell you how (the same way you would if you were taking your car in). There's really no reason *not* to report something that you know is wrong, in my opinion anyway. Even if it's not enough information to fix it, at least other people are aware that there is a problem.

Well, if you knew what was causing it, then you wouldn't need to report a bug as you could just fix it yourself :P Look, you know it's a kernel panic. You know kernels aren't supposed to panic.

They are reported all the time. And it probably doesn't take a *major* change to fix it. To the contrary, *major* changes typically introduce more bugs.

For example, My laptop has 4GB of swap. Why? Well, because I use hibernate and hibernate works on the swap partition and I want to make sure that I have enough swap to write all my memory to swap (actually It's now compressed so actually I probablldon't really need that much). > Wouldn't a sufficiently large swap (100GB for example) completely > prevent out of memory conditions and the oom-killer? No. oom killer kicks in when your system is out of virtual memory. Consider this example: You have 4GB RAM You have 0 swap. Therefore you have a total of 4GB virtual memory. The second all your processes try to consume more than 4G of virtual memory, oom killer will kick in* Consider the next example You have 4GB RAM You have 100GB swap. Therefore you have a total of 104GB virtual memory The second all your processes try to consume more than 104GB of virtual memory, oom killer will kick in. Oom killer works on virtual memory (RAM + swap). So it doesn't matter how much RAM you have or how much swap you have, when the total virtual memory is consumed, oom killer is called. The secret is to not run out of virtual memory. There is no *easy* way not to run out of virtual memory. You either don't consume as much VM, or you provide more VM (either through RAM or swap). * This is not entirely true, the system also needs memory for the kernel, buffers, hardware drivers, and other things which simply cannot be paged out to disk, so the actual number will be less than the amount of VM.

The *prime* example is you have a program with a memory leak (omg we have programs with memory leaks?). On a system with only say 2GB swap, that program will cause oom killer to kick in fairly quickly, on a system with 100GB swap, that system is going to have to use all 100GB of swap before oom kicks in. By then your system will probably be thrashing like hell. There is no way you can complete guarantee a system won't run out of virtual memory, unless you can guarantee that there are no misbehaving applications or that some clueless guy won't isn't going to try to open a database dump in vi.* * Well you could set process/user limits to make sure a process gets an error after it tries to allocate a set limit of memory.

I think you are just not understanding what is being said (or maybe just trying to over-generalize it). There is never a time I'm using 100G of vm at one time, so why do i need 100G of swap? Sure, I could create a 100G swap partition, but the kernel is *never* going to need to use 100G of swap at once (unless I have a *seriously* broken app), so why bother? Moreover, 100G is going to take a LONG time to swap in/out (remember disk is slower than RAM). What we are saying is, swap is good for certain conditions (which I don't feel like explaining again).

Maybe the pages from > stale processes never total more than a small amount? I don't see how > that could be Because you're (likely) never going to be using 100GB of memory at one time for all your processes, let alone "idle" processes, so what's the point of allocating all that swap? Continuing the analogy, it's like getting a stadium-sized attic that's 100x bigger than the house your building it on just to store a Christmas tree and a few other items. Here's another way of looking at it. The kernel wants to use *all* your RAM. RAM is fast (compared to disk). But it wants to use the RAM for stuff that's actually needed most at the present time. So say you have 4G RAM. You're only using maybe 1.5G memory for applications. So the kernel is going to try to use the remaining 2.5G for cache when/if it needs to. But let's say you're hitting the disk a lot because you're compiling something, then the kernel might decide it would like to cache more files than the 2.5G. So it sees you have 300M of paged in process memory that hasn't been used in a long while. A better use of RAM may be to swap out those 300M and use it for more filesystem cache, causing your compilation to run faster. But if you have a 100G swap file and only 300M of "idle" pages then all that extra swap isn't going to be of any use. Similarly, you don't want to swap out all of the 1.5G RAM because some of it is actually being actively used (e.g. by the compiler).

The rule of thumb is, if your disk is thrashing or you are getting ooms/locks then you need more RAM (or less memory-hungry processes).

Swap is not useful as filesystem cache. Swap is as efficient (probably a little less) than the files on the disk. It's RAM that's efficient as filesystem cache. Where swap comes in is the kernel can swap out pages from "stale" processes, and reclaim the RAM as filesystem cache. Think of it this way: You have a house with an attic. Now the attic is not as "efficient" as say, the middle of your living room. You have a Christmas tree, but you only use that Christmas tree maybe once a year. Now it's much more efficient to keep that Christmas tree in the attic for 11 months of the year and use that reclaimed space in your living room for.. say a coffee table. Then, when you need that Christmas tree in December, you pull it out of the attic and maybe put the coffee table up in the attic for a month. The Christmas tree represents a process that's just sitting out there doing not much half the time, but taking up space. The space in your living room is RAM, and the space in your attic is swap. The coffee table is filesystem cache.

My system is the same way. Right now I've got a 4GB system that's using 708MB swap. But vmstat isn't showing any swap activity. Why? Because some processes that I'm not aware about because I'm obviously not using, got swapped out a long time ago, and Linux is using that reclaimed RAM to compile chromium ;) If/when I need part of that 708MB becomes active, Linux will swap it back in in one short burst that I doubt that I'll even notice.

There's regular swapping and there is "thrashing". Thrashing is indicative of a memory-starved system, i.e. when many processes are trying to access memory, but there just isn't enough and the system is frantically swapping in/out. I'm talking about your normal day-to-day swapping that you probably don't even notice. > It gets so bad that you can't even run a shell properly to try and see > what's going on and kill the actual memory hog." Again, that is thrashing. I'm talking about "normal" swappage. Dont throw the baby out with the bath water. > Also, aren't you likely to wear out your hard disk sooner using swap? Is this coming from someone who uses Gentoo linux, which is constantly downloading/compiling/linking object files? Syslog and other loggers writing everything under the sun to a log file. Backups, journal writes, database transactions, etc. Compare how many disk transactions take place during your normal Gentoo usage versus a few megabytes here/there being swapped in/out. Again, I'm talking about regular swapping, not "oh my god I has no RAM and my hard drive won't stop" Even so, we're talking about modern drives here. This isn't the 1960s.

I don't see why it has to be one way *or* the other... Yes more RAM is always going to be better than more swap, RAM is just way faster than disk, however byte-per-byte, disk is cheaper. The whole reason why we have swap.. back in the olden days, some programs needed more RAM than perhaps the system provided. Some of these program were written with this in mind, and actually handled this by manually writing some of it's data to disk, then freeing that data from RAM, doing something, then when it needed the disk data, reading it back into RAM (after having freed the previous data). This is of course cumbersome. Enter virtual memory operating systems, which basically treat fast memory (RAM) and slow memory (disk) as one flat memory pool. Then the program it all looks like memory, and the OS does the paging in and out to disk. By now you would think "oh, but if I just had one system that had a more RAM than i would ever use simultaneously, then I don't need swap, right? Well, not exactly, because modern operationg systems also do something called filesystem caching. What this does is, recently, and often used (parts of) files on the filesystem are kept into fast RAM, so when a program needs that data it can be fetched from cached RAM instead of hitting slower disk. Ok, that's nice, but what does that have to do with swap? Well, not only does Linux keep track of wIt sounds like adding physical RAM is better than enabling swap in every way. I'll stay in the anti-swap camp.hat files are used often, it also keeps track of what pages of virtual memory are *not* used often. Say you started some program a long time ago, or some program launches at boot time, but that program sleeps and doesn't do anything for a long time. Now ordinarily that program would just sit there taking up RAM. Now you are running some other programs, and these programs are very actively hitting the disk. Now Linux would love to use more RAM for caching those disk hits, but that program you haven't touched in hours is taking up RAM doing nothing. That's where swap comes in. Linux would like to take that sleeping process and swap some of its pages out to disk, so it can use the freed RAM for more cache, and therefore speed up the programs that are actually being used. Then, if the barely used process ever does wake up, Linux can expire some cache and put it back into RAM. In this case swap *is* good because it's making more efficient use of RAM by swapping out seldom-used processes and using that RAM to cache often-accessed files. So a healthy combination of swap and RAM *can* be a good thing. If, however, you have so much RAM that you can run every program you'd ever run simultaneously with every file you'd ever access cached in RAM then I wouldn't worry about swap ;) -a

When I move to a different machine, I just * boot into a live cd * back up all the partitions with rsync (or use tar or similar if you need compression) to an external (USB) drive. * boot new machine into livcd * repartion, copy backed up files * install bootloader (and reconfigure/build kernel if necessary) If both source and target are on the same network you can probably also get away with rsync'ing over the LAN instead of using an external drive. As for what "technology" is best, they are not going to make a whole lot of difference, IMO. I find rsync/cp easier to work with (you can manipulate files before copying them to the new box). tar is more efficient if you need compression. dd, would be the least efficient in my opinion, because it's going to clone the entire partition, including unused blocks, when you're really only concerned about the files. Tools like partimage, etc. can clone a partition "smartly" but I tend to use those tools less often as I'm really only concerned about the files, not the partitions. Unless your source and target partitions are going to have the exact same geometry, I don't see the benefit if cloning partitions. Just my 2¢ -a
Re: [gentoo-user] Using KVM, what about clocks?

Well, KVM_CLOCK obviously: KVM_CLOCK bool "KVM paravirtualized clock" select PARAVIRT select PARAVIRT_CLOCK Turning on this option will allow you to run a paravirtualized clock when running over the KVM hypervisor. Instead of relying on a PIT (or probably other) emulation by the underlying device model, the host provides the guest with timing infrastructure such as time of day, and system time

Maybe '/home/user' was > at the very top of the long list that scrolled up the screen when I > ran the find command without -delete? > Well this is an unfortunate way to learn how find works. A better way would be: $ man find Basically find works of a chain of selection criteria. It crawls all the files/dirs and when one item in the chain is true for the criteria, it checks for the other. For example $ find /path -type f -name blah -print Crawls /path, for each file/dir it checks if it is a regular file (-type f), if that is true, it checks if it's name is "blah", if that is true, it prints the name (blah). Therefore, $ find /path -delete -type f -name Crawls path, then checks "-delete".. but wait, -delete evaluates to "true if removal succeeded" (find(1)), so it deletes the file, then checks to see if it is a regular file, then if that is true then it checks the name... but all that doesn't matter because your files are deleted. You should never put -delete at the beginning of a chain and, arguably, you shouldn't use -delete at all. It even says in the man page: Warnings: Don't forget that the find command line is evaluated as an expression, so putting -delete first will make find try to delete everything below the starting points you specified. When testing a find command line that you later intend to use with -delete, you should explicitly specify -depth in order to avoid later surprises. Because -delete implies -depth, you cannot usefully use -prune and -delete together.

I would just keep the original, but that's just me. Converting them you're going to lose quality to some degree or another. Just burn them to an optical disk or something.

[gentoo-user] Drupal appliance available
Last night I decided I wanted to create a new Gentoo virtual appliance. So I build a Drupal[1] appliance. Though I really don't know anything about Drupal, but I managed to get one made. I uploaded a "pruned" appliance. Which means I removed the gentoo toolchain, so it's not upgradable or manageable in the Gentoo sense. It's just the appliance. But I did so just to see how small I could make it. It turns out to be a 63M compressed vmdk[2] with 72 packages installed[3] (excluding virtuals). Anyway see below if anyone wants to play with it, and let me know if you have any suggestions. -a [1] http://drupal.org/ [2] http://starship.python.net/crew/marduk/drupal-dist.vmdk.bz2 [3] http://starship.python.net/crew/marduk/drupal-dist-package.lst

I see. I guess I don't consider one as "older". They are rather alternatives to one another (like openssl and gnutls).

Admittedly there isn't much difference, so if what you are using works for you why not stick with it. I still prefer encfs, although I have admittedly never tried ecryptfs, for the following reasons: * It's FUSE, completely userspace and requires no kernel support (other than FUSE) and no special privileges to mount (other than fusermount). * You can have multiple layers of encryption on on source directory. E.g. two different passwords can give you two different views of the filesystem. * In the documentation at least, it says when you upgrade ecryptfs you should first copy the files from the old ecryptfs to an unencrypted filesystem, and then copy it to the new ecryptfs. That seems like something some people won't want to do.

I can honestly say that I haven't experienced so much pain working with
libvirt/virt-manger. If I had I probably would have given up, but I've
been using it for years now.
What versions of packages are you using? Are you mixing stable/unstable

I can't really say. I've never seen that error before. What steps are
you taking to create the VM?

I don't see it happening though. I didn't want to comment on this thread (having been on both sides of the fence). But I will say this. The best thing about Gentoo is it's a "meta-distribution". It gives you more control and more ease to do things "your" way. I think people should learn to take more advantage of the latter. I do.

All that encfs knows about an encrypted directory is in *one* file on the source directory (.encfs6.xml). Once that file is gone, there is no such thing as an encfs. Having said that: One of encfs's Achilles heel is its dependency on the boost C++ library which is *very* sensitive wrt to API/ABI changes and the like. It also depends on OpenSSL which also shares this notoriety (although, in my experience, less so). So there is a possibility that an update to any of those packages may have broken encfs and you need to rebuild the package.

Python bindings for the above A command-line and shell interface (called virsh) libvirtd, which is a daemon helper used to manage virtualization platforms which don't have their own management service (such as kvm). virt-manager, is a seperate product. It is a GUI interface written in python that is used to talk to manage different types of virtualization platforms. It uses libvirt (its python bindings) to do this. Think of it as a GUI version of virsh. But you don't need virt-manager to use libvirt, and you don't even need libvirtd to use libvirt (e.g. you are interfacing with Xen or VMware hypervisors). That's why I was trying to say it's good for you to figure out what you are trying to do, before you go through the trouble of figuring out how to solve a problem that doesn't even pertain to you and could have been avoided altogether just by choosing the right combination of USE flags. If you are just wanting have a GUI for Xen, for example, you don't even need to worry about libvirtd.

So I'd start with that. If you are not going to use virtual networks, then you could simply disable the virt-net USE flag and save yourself some time. As for as iptables. You need the right sub-drivers (or whatever they're called). Basically if you are using virtual networking you need to be able to do NAT.

Other than the obvious (which is to check /var/log/messages or run without --daemon)... My guess is that you have enabled the virt-network USE flag but the system is not configured as such that it could start the default virtual network. Among other things you need: * iptables support in there kernel * bridging support in the kernel * tun/tap support in the kernel * brctl (probably a dependency of the package itself) * iproute2 (probably a dependency of the package itself) Did /var/log/messages tell you anything (did you bother to look)? Also libvirt has a log level that can be set in the config, you could increase that (and also check the logs). You should also check the logs. -a

I only pointed there because it had instructions on setting up KMS. KMS (kernel mode setting) does not require X. It gives the kernel the ability to set the modes of your graphics cards, more efficiently and usually beyond the capabilities of what the *vesa drivers can do. Perhaps a better, non X-centered explanation of what KMS is can be found here [1]. Regardless, KMS is the newer, better, what-all-the-cool-kids-are-doinger way to what we've traditionally called "framebuffer console". It also helps with X, especially switching between console and Xorg (faster and more seamless). It also gives you some xrandr-like abilities for the console. E.g. my laptop does native 1366x768 but does not support that vesa mode (it's not in the VESA standard afaik). But KMS can set that mode without me even having to specify it.[2] Anyway some proprietary X drivers (I've heard) don't support KMS (some still don't even support xrandr), but if you are not running Xorg then that may not be applicable to you anyway.

For the virtual appliances, I use a swap file instead of a swap partition, partially because I'm lazy and partially because it's easier to resize later on than a partition. The "." just means it's a standard "hidden" file per Unix convention[1] (i.e. you won't normally see if if you do "ls" but will if you do "ls -a". > Its hard to google because google doesn't recognize the .

It can serve a GNOME desktop via XDMCP or ssh. * hemp-node: This is almost like base, but applicable to my "hemp" project ( https://bitbucket.org/marduk/hemp ) . Hemp is kind of like a "cloud in a box". It's good for developing deployments via fabric * kde: This is just like the "gnome" appliance, except it serves KDE * lodgeit: This is a lodgeit ( http://www.pocoo.org/projects/lodgeit/ ) pastbin virtual appliance. We use this at my job. * teamplayer: this is another one of my projects. You can't really build it because it hasn't been released yet. But basically it's a "Democratic Internet radio station". We also use this at my job. * x: This is an "old-school" X appliance, like GNOME/KDE, except it serves TWM, xclock, xload, xterm, xeyes, etc. for a totally early 90's looking X desktop. * xfce: a "headless" XFCE desktop appliance. I'm actually looking for ideas for other Gentoo appliances. So if anyone has an idea for one, let me know. Also, if you happen to download and use the virtual appliance script (Makefile), there are many more options to build images including: * "headless" appliances (serial console) * virtio (for kvm-based VMs) * external kernel image (for kvm (and possibly others)) * Use dash instead of bash for the default shell * remove "build" (gentoo-critical) packages (e.g. gcc, portage, etc.). This will make it so you can't ever use portage on the appliance, but it reduces the size of the appliance greatly. * Use a static /dev instead of udev * Build and use binary packages so you don't have to re-compile everything every time you build a new image. * Build/use/distribute stage4 tarballs of the appliance. This really speeds up the creation of images too (e.g. I can build a "base" virtual appliance image on my laptop in less than 3 minutes. * Use a different kernel and/or different kernel config. * Creates raw images, compressed QCOW, VMDK, and XVA. I'd also welcome any other ideas for image-building features. -a

Sure. I did not mean to imply one *must* know about FEATURES in order to maintain a Gentoo system, only that it is a fundamental part of Gentoo that may be of interest to you (it's even mentioned in the Handbook). The --jobs parameter is not so important and, while it's been been a feature of portage for a while, it hasn't nearly been around as long as FEATURES (which has been part of Gentoo for as long as I can remember).

That's the inittab for getty running on a serial console.. should be disabled for non-headless. I'll need to fix that. > OH, and what does the `FEATURES=' entry in /etc/make.conf do? You've never heard of FEATURES (or --jobs)? May want to peruse the man pages a bit. FEATURES is a very fundamental part of portage (man make.conf). Will post when the inittab is fixed.

Thank you. I downloaded the xva.py script and created a target to create .xva files. The script appeared to run fine. No errors, but I cannot verify that the .xva is good. I used hvm and converted the raw image. The .xva is 4.1G whereras the original raw image is only 414MB (sparse). The .xva appears to be a tar file, but I guess w/o the -S flag passed to gnu tar.

Yes, of course a raw image file will typically be bigger than a compressed qcow, just as an unpacked stage4..tar.bz2 file is going to be bigger than the original archive. But in terms transferability, compressed qcows are more efficient since they only include *used* blocks and they are compressed. I can convert the image into any of a number of formats, but the issue then is it will be bigger, and thus take me longer to upload it and the OP to download it.

I have a program that I use to create Gentoo VM appliances. I have no idea if it works with vbox or vmware as I run KVM, but I think it *should* work. Anyway if you want to try it you can or, if you want, it also builds stage4 tarballs, so I can build you a stage4 tarball of a base Gentoo install pretty easily (including kernel). The stage4 (excluding portage) would be ~90MB (bz2). The disk image (compressed QCOW is about 120MB).

You are wrong. slots is the mechanism whereby "different versions of a single package can coexist on a system". "Setting a choice" I assume means your eselect-style choices. For example, you can eselect a pager, which has nothing do do with slots. Or you can eselect the system python, which does (indirectly) have to do with slots. But eselect and slots are not the same.

I have a bunch of systems (desktop and client) and none of them pull in any KDE libs save one, which has kde-meta in the world file. Not even my mythtv box, which need QT has any kde libs installed.

In the olden days (pre libc6?) believe it was required form them to be both executable and by whoever wanted to run (load) them. It's probably still a requirement for other *nix systems.

Gnome3 is slowly making its way into portage, and so so is bringing with it packages that depend either explicitly or optionally on gtk3, e.g. libunique-3.0.0 clutter-gtk libnotify-0.7.2 gtkmm-3.0.0.

Go into /etc/conf.d/rc and change RC_DEVICES to "static".

I'll never get it as small as yours... but still I *am* > interested in your memory-saving tricks :-) I'm not saying replace bash with dash. I'm saying change your login shell with dash (i.e. chsh). Moreover, dash is POSIX compliant so it should be able to be used with most shell scripts. The only reason you need bash around is that unfortunately baselayout-1 depends on some bash-specific features (like bash arrays), so you can't completely get rid of it. But for most stuff dash is fine.

Well, first the "challenge" did not require that it had to have any use. But thinking about what you said, I remember when I first started using Linux, it was not unthinkable to think that was enough memory to do stuff. So I decided to build another VM and actually install stuff on it. I thought about what I'd typically be running on my desktop. Being that this is a graphics-less machine, I installed non-gui equivalents: * mutt for email * irssi for irc * vim for text editing * pidgin (finch) for IM * lynx for browsing the web * screen for multi-tasking Then I added a NIC so that I could actually get on the network. Interestingly enough, adding the virtio NIC made the VM jump up to 18MB on the initial boot/shell, but adding a non-virtio NIC kept it down to 3MB. Then I added a regular user and did "typical" things: marduk@lilpenguin $ ps -ef |grep ^$USER marduk2081 2080 0 21:36 ttyS000:00:00 -dash marduk2094 2081 0 21:36 ttyS000:00:00 screen -T vt100 marduk2095 2094 0 21:36 ?00:00:02 SCREEN -T vt100 marduk2096 2095 0 21:36 pts/000:00:00 -/bin/dash marduk2101 2096 0 21:36 pts/000:00:00 mutt marduk2102 2095 0 21:37 pts/100:00:00 -/bin/dash marduk2107 2102 0 21:37 pts/100:00:00 lynx http://m.reuters.com/ marduk2110 2107 0 21:37 pts/100:00:00 [lynx] marduk2111 2095 0 21:37 pts/200:00:00 -/bin/dash marduk2116 2111 0 21:38 pts/200:00:00 vim helloworld.py marduk2117 2095 0 21:38 pts/300:00:00 -/bin/dash marduk2122 2117 0 21:38 pts/300:00:00 irssi marduk2124 2095 0 21:41 pts/400:00:00 -/bin/dash marduk2129 2124 0 21:41 pts/400:00:00 finch marduk2131 2095 0 21:42 pts/500:00:00 -/bin/dash marduk2149 2095 0 21:43 pts/600:00:00 -/bin/dash marduk2154 2149 0 21:43 pts/600:00:00 ssh tanuki@victoria marduk2176 2131 0 21:46 pts/500:00:00 ps -ef marduk2177 2131 0 21:46 pts/500:00:00 grep ^marduk marduk@lilpenguin $ free -m total used free sharedbuffers cached Mem:33 28 5 0 0 9 -/+ buffers/cache: 18 14 Swap:0 0 0 marduk@lilpenguin $ netstat -tn|grep ESTABLISHED |wc -l 5 So, running screen (with 7 sessions), 8 dash shells, mutt, irssi, finch, an ssh session, lynx, vim and 5 TCP connections open still only takes up 18MB RAM (excluding cache). Still not bad.

I could probably get it lower by tweaking the kernel a bit more. Also it would probably use slightly less RAM if it were 32-bit. Also, the biggest user of memory are /bin/bash and /bin/login. I could minimize memory further by making the login shell ash or dash.
