EFI entry got removed after system reconfigure

EFI entry got removed after system reconfigure

[Roel Janssen]

Dear Guix,

I ran:
$ guix system reconfigure /etc/config.scm

Which succeeded.  Then rebooted, to find that my computer wouldn't boot
anymore due to a missing EFI entry.

So I created a new entry from a LiveUSB using “efibootmgr” to boot into
GuixSD again.  Is this a known problem, and will it happen again when I
reconfigure the system?

Kind regards,
Roel Janssen

Hi Roel,

this shouldn't happen. Can you share your configuration?

I had this issue a long time ago. [1]

I didn't take an attention on output as I remember.  Did you?  :-)

This looks like the same issue.  And that “efibootmgr” command looks
awfully familiar :).

I didn't pay enough attention to the output of 'guix system reconfigure'
to notice anything strange, so I don't know if a problem had been
indicated.

Kind regards,
Roel Janssen

I came across this too recently, because of a bug in the efivar package
that affects some platforms:

https://github.com/rhboot/efivar/issues/111

So I downgraded it in 887fe1fbde7d72788ec348ab4665e1df3d0d704f.  Which
commit did you run the reconfigure command on?

A bigger problem is that GRUB will happily wipe the bootloader entry,
proceed to try to make a new one which fails, and then exit with status
code 0.  I wonder if this has been reported upstream.
