Continuing this issue from https://issues.guix.gnu.org/issue/36878

guix reconfigure recently broke GRUB for me. When rebooting I get
dropped to a "grub rescue>" shell with an error about
"grub_file_filters" being an unknown symbol.
If I try doing the usual commands to tell GRUB how to boot I just
see the above error repeated, or "unknown command" when I run
things such as insmod or "configfile".

So to fix the problem I can boot to a Guix install disk and do
"guix init" which rebuilds the system using older package
definitions from the disk.
That allows me to get a working system, but if I do another
"guix pull" and reconfigure using the same config file it breaks
GRUB again when I reboot. "guix describe" shows that my latest
attempt was with commit 35600cd.

Here is the bootloader and filesystem sections of my config:
  (bootloader (bootloader-configuration
                (bootloader grub-efi-bootloader)
                (target "/boot/efi")))
  (file-systems (cons* (file-system
                         (device "/dev/sda2")
                         (mount-point "/boot/efi")
                         (type "vfat"))
                       (file-system
                         (device (file-system-label "guixsd-root"))
                         (mount-point "/")
                         (type "ext4"))
                       %base-file-systems))

I should make a note that I usually don't use efi, and I'm not
completely confident it's all set up properly. I do have a
"BIOS boot" partition on /dev/sda1 too, is that even needed with
efi? Although, I have been using this setup, and the above
definitions, for about 6 months now without any bootloader or
filesystem issues. And the same config is being used to fix the
system when GRUB breaks as well as to reconfigure afterward
(causing the breakage). So my guess is some new update is the
culprit.

Hi ison,

Thanks for opening a new ticket for tracking this.

This narrows it down quite a bit -- I suspect that we're broken for

'grub-efi-bootloader', since I've been able to successfully reconfigure

with 'grub-bootloader' on both of my machines.

I don't believe so. I think the ESP partition on /dev/sda2 is all you

need.

It certainly sounds like it, and I'm the last person to have touched the

bootloader installation code :)

I'll look into this ASAP. Thanks again for the bug report!

Hi ison,

I wasn't able to reproduce with an OVMF virtual machine, but the

symptoms you've described lead me to suspect that the issue concerns

improper installation of a GC root for grub. Would you be willing to see

if the patch provided by #36947 fixes your issue?

Regards,

Jakob

Hi,

I've examined /var/guix/gcroots without #36947 and I get:

lrwxrwxrwx 1 root root 18 24. Jul 11:32 profiles -> /var/guix/profiles

lrwxrwxrwx 1 root root 19 24. Jul 11:32 current-system -> /run/current-system

lrwxrwxrwx 1 root root 18 24. Jul 11:32 booted-system -> /run/booted-system

lrwxrwxrwx 1 root root 26 29. Jul 22:26 bootcfg -> //var/guix/gcroots/bootcfg

So I guess I'm one "guix gc" away from also destroying my installation.

The double slash looks very suspicious...

Was this fixed after applying #36947?

Any reason in particular? The second slash is there because
'%gc-roots-directory' has a leading slash, and that gets appended to
'target', which in this case is '/'.

I'm sorry to report that it actually didn't fix the problem.

Also I don't know why it didn't occur to me to mention this detail
before, but the reason I previously thought the message mentioned
in bug#36878 was important is because it's actually the very last
thing I see on the command line after reconfiguring. The line I'm
talking about is of course:
shepherd: Evaluating user expression (let* ((services (map primitive-load (?))) # ?) ?)

I'm pretty sure even if that message is normal, it's not normal
for it to be the last line you see.
Perhaps the reconfigure is dying at that point, or some point
shortly after, without outputting any other errors.

I'll continue to investigate; perhaps I'll be able to reproduce if I

copy your exact partition scheme in the virtual machine. I'm sorry that

you had to go through that whole 'guix init' spiel again.

Do you see a "bootloader successfully installed on ..." message earlier
in the output? 5c8c8c455 changed the order that things are done in so
that services are upgraded after the bootloader is installed.

After some further research, I was able to create a virtual machine with

the partition scheme and bootloader configuration that you described.

;; This is an operating system configuration template ;; for a "bare bones" setup, with no X11 display server. (use-modules (gnu)) (use-service-modules networking ssh) (use-package-modules screen) (operating-system (host-name "komputilo") (timezone "Europe/Berlin") (locale "en_US.utf8") ;; Boot in "legacy" BIOS mode, assuming /dev/sdX is the ;; target hard disk, and "my-root" is the label of the target ;; root file system. (bootloader (bootloader-configuration (bootloader grub-efi-bootloader) (target "/boot/efi"))) (file-systems (cons* (file-system (device "/dev/sda2") (mount-point "/boot/efi") (type "vfat")) (file-system (device (file-system-label "my-root")) (mount-point "/") (type "ext4")) %base-file-systems)) ;; This is where user accounts are specified. The "root" ;; account is implicit, and is initially created with the ;; empty password. (users (cons (user-account (name "alice") (comment "Bob's sister") (group "users") ;; Adding the account to the "wheel" group ;; makes it a sudoer. Adding it to "audio" ;; and "video" allows the user to play sound ;; and access the webcam. (supplementary-groups '("wheel" "audio" "video"))) %base-user-accounts)) ;; Globally-installed packages. (packages (cons screen %base-packages)) ;; Add services to the baseline: a DHCP client and ;; an SSH server. (services (append (list (service dhcp-client-service-type) (service openssh-service-type (openssh-configuration (port-number 2222)))) %base-services)))

However, I still cannot seem to reproduce this issue with the most
recent master. Everything boots fine. I've extracted the bootloader
installation "script", and everything appears to be normal to me.

(begin (use-modules (gnu build bootloader) (gnu build install) (guix build utils) (guix store) (guix utils) (ice-9 binary-ports) (srfi srfi-34) (srfi srfi-35)) (let* ((gc-root (string-append "/" %gc-roots-directory "/bootcfg")) (temp-gc-root (string-append gc-root ".new"))) (switch-symlinks temp-gc-root "/gnu/store/xlb81742i5sb4cdmidfhabprc17ijwck-grub.cfg") (install-boot-config "/gnu/store/xlb81742i5sb4cdmidfhabprc17ijwck-grub.cfg" "/boot/grub/grub.cfg" "/") (when #t (catch #t (lambda () ((lambda (bootloader efi-dir mount-point) (let ((grub-install (string-append bootloader "/sbin/grub-install")) (install-dir (string-append mount-point "/boot")) (target-esp (if (file-exists?

To the rest of guix -- I would really appreciate some help here. I'm not

sure what else I can do for working on this bug report.

Jakob

Sorry it took me so long to reply, I didn't have access to the
broken machine until now. As you requested here is the partitions as
listed by parted:

Number  Start   End     Size    File system     Name    Flags
 1      1049kB  3046kB  2097kB                  grub    bios_grub
 2      3146kB  540MB   537MB   fat32           efi     boot, esp
 3      540MB   2588MB  2048MB  linux-swap(v1)  swap
 4      2588MB  750GB   748GB   ext4            guixsd

/boot/efi looks ok as far as I can tell at least. It's tree is:
/boot/efi/
??? EFI
    ??? grub
    ?   ??? grubx64.efi
    ??? Guix
    ?   ??? grubx64.efi
    ??? GuixSD
        ??? grubx64.efi
All 3 grubx64.efi files differ from each other and are around 120kb.

====================================================================
But considering you can't reproduce the issue would it be a good
idea for me to reinstall and see if I can even reproduce it?
Although I think this time I would leave off the bios_grub partition
I'm willing to keep testing the current bug if it's important or
indicative of a more serious problem. But please don't feel
obligated to keep working on this just for me, I'm perfectly fine
just reinstalling. The issue doesn't seem to affect my desktop
anyway, I was able to upgrade it smoothly.

It's always possible the issue was caused by some strange
combination involving the patched bug, from earlier in the
discussion, and my weird partition layout. Might not even be worth
investigating unless it happens to someone else
(or me again after a fresh install).

Hm. Nearly the same as what I had, though my partitions had different

sizes and I didn't have a swap partition. I may try again with this

exact setup when I get back to the United States just to see what

happens.

Interesting... I only have '/boot/efi/EFI/Guix'. Do you have a

'/boot/grub'?

I think it may be indicative of a more serious problem, since you

mentioned that this was fine up until the commit refactoring 'guix

system reconfigure'. If you're willing to reinstall and see if you can

reproduce it, that maywould be helpful -- you could send me the relevant

'install-bootloader.scm' store item if it breaks again.

Thank you very much, ison. I appreciate your cooperation here greatly.

Jakob

I do have a /boot/grub actually. Is that strange?

It looks like a normal /boot/grub to me, and contains a grub.cfg

Sounds good, I'll reinstall it over the weekend

I think that's normal -- my virtual machine had one, too.

So I attempted a re-install and surprisingly it still fails.
I attempted 3 times. Using the graphical installer without efi,
manual install without efi, manual install with efi. All downloaded
and built everything successfully only to fail at the bootloader.
If the problem was my config then I'd think my first attempt would
have succeeded because the graphical installation automatically
built the config file.

At least it's giving an error this time:
error: '/gnu/store/drz35fc...-grub-efi-2.02/sbin/grub-install --boot-directory /mnt/boot --bootloader-id=Guix --efi-directory /boot/efi' exited with status 1: output follows:
  /gnu/store/drz35fc...-grub-efi-2.02/sbin/grub-install: error: /gnu/store/drz35fc...-grub-efi-2.02/lib/grub/i386-pc/modinfo.sh doesn't exist. Please specify --target or --directory.

My bootloader is section is still:
  (bootloader (bootloader-configuration
               (bootloader grub-efi-bootloader)
               (target "/boot/efi")))

This is perfect (I mean, not that it still doesn't work, but that we
have some error output). I think I know what's going on. The new 'guix
system reconfigure' uses G-Expressions, and it looks like Grub is being
ungexp'd for the wrong architecture. To be sure, what's the architecture
of this machine?

I'll investigate further and let you know what I find. Thanks again for
doing this.

Regards,
Jakob

That's great, thanks for investigating this.

Both the machine architecture and the liveUSB are x86_64.

The message above is telling that it’s trying to do a “BIOS” (as opposed

to EFI) install of GRUB, but you specified ‘grub-efi’, hence the

failure.

Is your system really EFI?

Anyway, this issue is different from the original one, so perhaps we

should discuss it on help-guix?

Thanks,

Ludo’.

Closing, because this is apparently the same as
https://issues.guix.gnu.org/issue/36865, which fortunately was fixed a
while back!

Thanks,

For the record I attempted another install just now and it was

successful. I'm not sure exactly what caused the initial breakage or

what fixed it, but I'm glad it's working now.

Thanks again for the help.
