'guix gc' as user makes system unbootable.-

I had executed 'guix gc' and then 'guix package -i blender' and then
'guix package -u', all as user without running 'guix pull' recently
(did it last week). When rebooting, current GrUB boot menu entry did
not work. But previous versions (#1,#2,#3) worked at different
levels. Below each menu entry I post my experience upon boting with
it:

menuentry "GNU with Linux-Libre 4.12.9 (beta)"
Kernel panic

menuentry "GNU with Linux-Libre 4.11.6 (beta) (#1, 2017-06-21 18:01)"
No GUI. Lost keyboad configuration on tty's. Logged in as user. The
output of 'sudo herd status' was 'error: connect:
/var/run/shepherd/socket: No existe el fichero o el directorio'.

menuentry "GNU with Linux-Libre 4.11.6 (beta) (#2, 2017-06-22 15:49)"
Working GUI (no local keyboard as usual) and working Herd. Lost keyboad configuration on tty's.

This situation has happened before and has, as in this time, made my
installation unbootable. But I did not notice that it was because of
'guix gc', until now. Is it normal that a user can affect the boot
process for the whole operating system?

Could you please show us the output of this command:

ls -l /var/guix/profiles/system*

Has the disk label changed?

Did you remove anything under /var/guix/profiles/ before running “guix
gc”?

I had a similar situation today. guix gc removed the grub background png
from the store. the one, that was used by /boot/grub/grub.cfg. the boot
menu then had a black and blue background. rebuilding the configuration
refetched the background image, but guix gc removed it again.

after rebooting and reconfiguring a few times 'fixed' it. I will report
back, if I should be able to reproduce.

Normally the current ‘grub.cfg’ is a GC root, which prevents the
background image and other items from being deleted:

Like I said, I cannot reproduce currently. guix gc --list-dead doesn't
mention grub files anymore.

below you see what I wrote while doing stuff. it starts with a missing
bootcfg, then doing stuff and at '--- end' I start again with a bootcfg.

--- start missing bootcfg

$ ls /var/guix/gcroots
auto/ booted-system current-system profiles

I don't have bootcfg in there.

$ guix --version
guix (GNU Guix) 02345c963e1e8a45afcdf5acb80fca4538244b36

I remember something strange: when I reconfigured my system, the 'old
generations' menu in grub kept having 11 entrys. It overwrote e.g. entry
7 and entry 8 then was the oldest one. I don't _remember_ switching to
an older entry, which would explain that, but that seems to be the only
explanation. Maybe the overwriting of an older generation made the grub
files dead? I often, but not always, use --no-bootloader.

While writing, I try to switch to an older generation, reconfigure (to
overwrite one generation) and see what happens.
the switching did something surprising:
$ sudo guix system switch-generation 5

'https://berlin.guixsd.org'... 100.0%
substitute: updating list of substitutes from
'https://mirror.hydra.gnu.org'... 100.0%

# error about grub-install failing, because ext2 doesn't support embedding
$ sudo grub-install --force /dev/sda3

why does guix need to download something to get to an old configuration?
those things should still be in the store!

then reconfiguring using my config from the latest generation downloadad
again things. This might be because updated guix since I build that
generation. but switching to an older generation should not need to do
that. that makes rollbacks not real rollbacks, right?

guix-gc still looks fine.
the youngest generation is now 6. (side note: in grub.cfg, the date of
the 6th generation is still the same. I remembered something different
above. is this wanted behaviour? I just realized, that a system
configuration, that depends on grub.cfg. is not deterministic from the
config.scm. It depends on prior entries in grub.cfg. is that the reason
there is (or should be) bootcfg in /var/guix/gcroots ?)

reboot. guix gc --list-dead looks good.

--- end

somehow, the grub.cfg now has the dates updated.

$ ls -l /var/guix/gcroots/bootcfg
lrwxrwxrwx 1 root root 52 18. Dez 13:36 /var/guix/gcroots/bootcfg ->

$ diff /var/guix/gcroots/bootcfg /boot/grub/grub.cfg
see diff [1] below


let's switch to the newest generation and try from there:

# guix system switch-generation 14
substitute: updating list of substitutes from
'https://berlin.guixsd.org'... 100.0%
substitute: updating list of substitutes from
'https://mirror.hydra.gnu.org'... 100.0%

$ diff /var/guix/gcroots/bootcfg /boot/grub/grub.cfg
## no-output, grub.cfg has still the same content->
/var/guix/gcroots/bootcfg changed
# guix system reconfigure confs/config.scm
## mentions expected grub error
$ diff /var/guix/gcroots/bootcfg /boot/grub/grub.cfg
see diff [2]

it does not seem to update /var/guix/gcroots/bootcfg.
and bootcfg somehow lists the generation number in the default entry.

what's going on here?

Martin

Under what circumstances did you have a system without

Are you saying that ‘guix system switch-generation’ does not update the
target of the /var/guix/gcroots/bootcfg symlink? (From a quick look at
the code it seems to update it.)

I cannot tell. I had some fs errors and run e2fsck several times. Maybe
that removed the link? But since then, I had done several reconfigures.
I'd expect those to recreate it again.

No, if you read it again, you see that 'switch-generation' updates it
correctly. 'reconfigure' doesn't seem to update it!

Okay, this shows us that the system generations are all still there. It
would help to know what exact error you get when the system fails to
boot.

That is very true. But it is strange that it happens to me always when
running 'guix gc'. Perhaps the previous times I had this problem was
with root. But this time I have not touched root.

Yes. It is weird. Nevertheless, it happens; that is undeniable. I can

I checked all .scm files used for 'guix system reconfigure
config.scm'. All have the 'my-root' label for root partition. e2label
shows root partition (/dev/sda2) has 'my-root' label.

I did not touch config.scm or have run 'sudo guix system reconfigure
config.scm' in months (as you can probably see from the kernel I am
using). This problem is recent and presented only after running 'guix
gc' as a non-root user.

I understand you doubt that this happens because guix is not supposed to
do it. I know I could have missed something, but I doubt it. Please g

Please try to compress them more. A few 100KiB is OK.

The picture you posted roughly shows:

The group.lock error above suggests it’s an old generation before commit

Apart from that last line I don’t see anything to worry about.

Are you sure you paste the log of this very generation where “sudo herd
status” fails?

I don’t doubt you’ve stumbled upon a bug! I’m just trying to isolate
the various issues, and here it’s just too fuzzy for me to draw any
conclusion.

Do you have a working GuixSD configuration based on a recent-ish master?
Or a clear failure with a recent GuixSD configuration?

We should focus on just one issue at a time.

Thank you,

Hey,
Sorry to bother you guys, but I'm having trouble leaving this email list...

I've tried logging into the web interface, and that failed.

I tried emailing guix-devel-leave@gnu.org, and that didn't seam to work.

Can someone help me leave this email list?

Thanks,

Joshua

Looking at guix/scripts/system.scm, ‘install-bootloader’ definitely
installs the ‘bootcfg’ symlink, except if ‘grub-install’ fails—which is
apparently the case in your transcript above.

Why did you write “expected grub error”? A GRUB error is never
something one should expect. :-)

Ok, makes sense.

I have currently set up /dev/sda3 as grub target, which is an ext4
partition. Since grub doesn't support embedding in ext, it fails. One
has to manually 'grub-install --force /dev/sda3'.

Good thing that you explained this. This is important for the other
issue in thread 'Dualbooting with guixsd not handling grub installation'.

Has the person who had the unsubscription issue already solved the
specific problem? I'm sending this message to person anyways, if you
received it twice, then you are still subscribed.

Can some list administrator confirm if the person is already
unsubscribed?

Finally, Joshua, I think we are discussing in bug-guix mailing list, not
guix-devel (I can see this because if I choose to reply to group, my
email client writes bug-guix email address in the To field of my
message).
