I think it was the upgrade to net-dns/openresolv-3.3.2 which was responsible. The solution was to edit etc/resolvconf.conf and uncomment the line name_servers=127.0.0.1

Only in a way that it is tmpfs as well. /tmp is rarely used and then mostly for stuff like different IPC pointers like unix sockets, which lay no burden on any disk. I've seen some suggestions of mounting /var/tmp/portage as tmpfs hovewer, but the logic of it escapes me: you loose persistency for nothing - any free memory will be used for FS cache anyway, so if emerge is working on these files they'll be 99.9% in-memory anyway. I only found it useful for RAM-challenged machines which can't spare any megabytes for FS cache so I'm mostly curious about it's application in home-like environment, as well. -- Mike Kazantsev // fraggod.net signature.asc Description: PGP signature

Just what do you > have under root? How did you format the rest? ext4 or reiserfs for root. reiserfs for portage and tmp (usually used by ccache). I choose reiser here because it has the best small-file performance, can use tail packing to save space on working with small files and you never ever have to worry about inode shortage. ccache, portage and tmp/portage are thousands of small files. On this laptop: /dev/mapper/aux-root on / type reiserfs (rw,noatime,nodiratime,acl) [ 5.2G / 10G ] /dev/sda1 on /boot type ext3 (rw,noatime) [ 114M / 183M ] /dev/mapper/prime-varz on /var type ext4 (rw,noatime,nodiratime) [ 519M / 2G ] /dev/mapper/prime-core on /home type ext4 (rw,noatime,nodiratime) [ 4.8G / 10G ] /dev/mapper/aux-extent on /mnt/extent type ext4 (rw,noatime,nodiratime) [ 6.6G / 10G ] /dev/mapper/aux-stash on /mnt/stash type reiserfs (rw,nosuid,nodev,noatime,nodiratime) [ 8G / 30G ] /dev/mapper/aux-tmp on /var/tmp type reiserfs (rw,noatime,nodiratime) [ 3G / 10G ] /dev/mapper/aux-portage on /usr/portage type reiserfs (rw,noatime,nodiratime) [ 800M / 3G ] /dev/mapper/aux-iwd on /mnt/stash/wine/iwd type xfs (rw,noatime) [ 2.2G / 5G ] /dev/mapper/aux-fallout on /mnt/stash/wine/fallout type xfs (rw,noatime) [ 600M / 5G ] "prime" is an LVM group on encrypted (dmcrypt) partition (/root and /etc repository are symlinked to /home). /opt and /usr/games are symlinked to /mnt/extent/, since they are quite heavy. xfs lvs are case-insensitive, so it allows to use any native linux tools (like WeiDU) on wine-accessed files, without having to convert their case.

[gentoo-user] Optimizations for SSD netbook
My girlfriend is at her wit's end with her SSD netbook and is now hogging my laptop. Her netbook has 1GB RAM that could be upgraded to 1.5GB, but I've read that it's a pain. It already runs xfce4, and I've just made these optimizations based on past discussions: 1. CFLAGS="-march=prescott -0s -pipe -fomit-frame-pointer -ssse3" 2. added elevator=noop as a boot parameter 3. disabled DRI to save 32MB RAM 4. removed the swap partition from /etc/fstab Am I missing anything significant? I've read that it's good to set up /tmp in RAM. How can I do that? In /etc/fstab I have: shm /dev/shm tmpfs nodev,nosuid,noexec Is that related? - Grant

Synced two ~x86 today and one more two days ago, but can't confirm the issue - everything seem to be working fine.

[gentoo-user] How to feed the watchdog?
Hi, I recently bought a MSI GM-IM45 [1] mainboard which includes a (hardware) watchdog timer. Now the problem is that I don't know how to prevent it from resetting the system. There seem to be two possible ways but I'm unable to make either one of them work... 1. There is a BIOS setting to enable/disable the watchdog: When I set it to a specific time it resets after the set interval, but when I disable the watchdog the reset still occurs (I don't know the exact interval yet and I'm unsure if it stays the same). So no luck here. 2. Feed the dog: I don't know what kind of watchdog it is so I don't know which driver I should use. I tried a live CD where I modprobed each of the watchdog driver modules (one at a time) and then wanted to prevent it from resetting with a looped "echo 1 > /dev/watchdog" with no success. There is some information on the watchdog timer in the user manual [2] on page 64 f. including some assembler code. But I'm not able to get something useful out of it. Any clue on this would be very appreciated, especially: - Why the BIOS setting won't work as expected - How to find out which watchdog chip it is - If the "echo 1" should work when I've found the right driver regards Roman [1] http://eu.msi.com/index.php?func=proddesc&maincat_no=388&prod_no=1526 [2] http://eu.msi.com/index.php?func=downloadfile&dno=8850&type=manual
[gentoo-user] Sync'ed my ~x86 system yesterday and now resolver stopped working
Hi, I have synced my ~x86 system yesterday and after it completed, the resolver doesn't work for some programs anymore. For example, ping says "unknown host name". It doesn't even contact the dns server, which is running on the same host. But dig works fine. Also, using the IP address directly, I can access the internet. I am suspecting that the new glibc 2.10 is causing this. Anybody else having this issue? -- Timur

This is what is in mine: # NOTE: The next line is critical for boot! none/procprocdefaults0 0 # glibc 2.2 and above expects tmpfs to be mounted at /dev/shm for # POSIX shared memory (shm_open, shm_unlink). # (tmpfs is a dynamically expandable/shrinkable ramdisk, and will # use almost no memory if not populated with files) # Adding the following line to /etc/fstab should take care of this: none/dev/shmtmpfsdefaults0 0 >From that I gather that the system won't boot without /proc and that glibc requires /dev/shm for some reason or other.

Stroller writes: But, surely "-march=" also instructs gcc to support the additional instructions. Suggest you re-read Daniel's post that I was replying to. What's the difference between supporting the "certain set of instructions" with "-march=" and doing so with USEs? One is for telling gcc how to compile C code, the other is for telling packages what inline assembler code is legal. In the case of mplayer, just setting mmx/sse/etc does absolutely nothing. You also have to enable custom-cpuopts, which then tells mplayer to ignore its own build-time detection of CPU features and only use the ones you tell it. Either way, if mplayer does it automatically or you pass in USE flags, all they do is enable selected asm files in the codecs that use those opcodes. --K
