I wonder. Is mount order deterministic at boot? Is it possible that
you're trying to activate the swap files before the underlying file
systems are mounted?

Cheers,

Yes, that's an issue ... there's two swap files.  One is on the root 
dir

and that one is the only one that came up active when I started the
system this morning.

The other one is on a mounted fs.  Earlier, I'd had it on the following
line to that fs, and as an admittedly feeble attempt, I moved that
swapon to the bottom of the file - who knows if those lines are
processed sequentially.  But it didn't help.

But, the thing is, the swap partition is also not mounted by its fstab
entry.  That wouldn't need an fs to be mounted.


As a workaround you can add swapon -a to local.start ...

That is generally my understanding as well, at least for
desktop/server situations when you're buying parts.

For a laptop you really have to look at the whole package.  Raw CPU
perf-per-dollar is often not the biggest concern with a laptop.  As
long as it meets your performance specs you're mostly going to be
worried about form, battery, and so on.  So, I really wouldn't obsess
over AMD vs Intel.

I have been buying all AMD lately for my regular hosts and do my own
builds.  My only recent laptop is a combo form that runs Intel,
because it was the form I wanted (Acer Switch running Win10 and a
bunch of Win-specific software).  You're probably going to find more
Intel options in this space in any case.

My thoughts on the same topic:

I have not seen *laptop* OEMs offering BIOS/UEFI firmware updates (which would 
include any applicable CPU microcode updates) for any longer than 18 months 
from the day of releasing their laptops onto the market.  Desktop MoBo OEMs 
are usually better, I've received firmware updates on ASUS MoBos for 5 years 
or so, with continuous improvements on stability and performance.

If the laptop's MoBo firmware is flash-able with coreboot you're in (partial) 
luck.  You still need microcode binary blobs and for these you are at the 
mercy of the CPU manufacturers.  With the Intel debacle over the last couple 
of years I realised their interest to keeping us as customers is limited to < 
5 years.  Beyond that they expect us to throw our PCs in the recycling bin and 
buy their latest offering, which errm ... hold on!  o_O  As we just found out 
Intel's latest ROM offering is compromised straight off the production line 
and given their prior form I wouldn't think they would rush to recall and 
replace their borked hardware any time soon.

Are AMD that much better?  They probably are, but not by much.

Both Intel and AMD are now only offering CPU/APUs with embedded OOB 
coprocessors (ME/PSP) and many of the vulnerabilities revealed over the last 
few years are caused by these backdoors at the heart of the PC.

Since I don't feel comfortable running a machine designed to be controlled/
controllable remotely before my OS of choice has even booted up, I am not keen 
on spending my money with either of these corporates.  At some point I'll look 
at saving up for a POWER9 workstation, which at least runs coreboot, but I 
have no solution at this stage for a laptop and not much hope Intel or AMD are 
going to change their design policy anytime soon.

[gentoo-user] New laptop - AMD or Intel?

[Mark Knecht]

In light of recent news and the 2 threads here about AMD and Intel
vulnerabilities I of course would have my only Windows machine apparently
start to die. As it's quite old, circa 2006 or so, I'm forced to at least
consider purchasing something to replace it.

This machine has only been used over the last 3-4 years for a few Win 10
recording studio music applications. That's likely to be true for the
near-term future but would eventually run Linux if I manage to get rid of
these last few holdouts. There's no financial data on it and very little
that's personal but it does reside on the main network in my home. It's not
generally used for browsing the web in any general way although it has been
used in the past to download soft synth patches and updates from music app
vendors.

My reading of the two recent threads are that neither is likely to be a big
problem for a closed hardware platform like a laptop, and especially for a
machine at home, but forced to choose I should probably go with an AMD
machine at this time.

Would that be the consensus of the group here?

thanks,
Mark

[gentoo-user] NFS trouble

[Peter Humphrey]

Hello list,

I decided to have another go at fixing my nfs setup. The host 192.168.1.4
exports its portage directory to this host, 192.168.1.5. I used to use nfs-v3
for this, but it wasn't working right so I'm trying with v4.

The problem is that, every time I tell this machine to mount the remote
directory, the server insists that it doesn't exist. I can't see what I've
missed. Here's some detail:

mount -t nfs 192.168.1.4:/mnt/nfs/portage /mnt/clrn/usr/portage # script on the 
client

Result:
* Mounting chroot dirs under /mnt/clrn ...
mount.nfs: mounting 192.168.1.4:/mnt/nfs/portage failed, reason given by 
server: No such file or directory

$ cat /etc/exports  # on the server
/mnt/nfs \
   
192.168.1.5(rw,sync,no_subtree_check,anonuid=250,anongid=250,crossmnt,fsid=0)  
/mnt/nfs/portage \
   
192.168.1.5(rw,sync,insecure,nohide,no_subtree_check,all_squash,anonuid=250,anongid=250
/mnt/nfs/port.resc \
   
192.168.1.5(rw,sync,insecure,nohide,no_subtree_check,all_squash,anonuid=250,anongid=250

$ sudo exportfs -v  # on the server
/mnt/nfs
192.168.1.5(sync,wdelay,hide,crossmnt,no_subtree_check,fsid=0,anonuid=250,anongid=250,sec=sys,rw,secure,root_squash,no_all_squash)
/mnt/nfs/portage

192.168.1.5(sync,wdelay,nohide,no_subtree_check,anonuid=250,anongid=250,sec=sys,rw,insecure,root_squash,all_squash)

Can anyone see the problem?

No one even agrees on what "stable" means, so I can't make any promises.
But ideally, the maintainer would determine which of the two cases ("I
forgot" or "this package is junk") applies and make a decision based on
that.

But maybe the person who maintains ebuild does not have enough time to
ensure that all QA requirements are met. E.g. installing (willingly) an
unstable package is not the same as installing a "stable" package that
in fact is not.
