Hello Guix,
I'm using a Guix system with the efi-bootloader-chain [1]. The chain
loads m1n1 (the Asahi Linux boot loader), u-boot and then grub.
A system roll-back used to work fine, but it stopped to work a while
ago. I'm not sure when that happened, because I rarley needed to
roll-back. But now that I don't have it anymore, I'm a bit nervous.
When I do a roll-back, this is what happens:
```
$ sudo guix system roll-back
Password:
guix system: error: efi-bootloader-chain: no such bootloader
```
It looks like the efi-bootloader-chain can't be found in the
%bootloaders variable of the (gnu bootloader) module. But that seems
strange, since it is defined in the same file (just a bit later).
Any ideas?
Thanks, Roman.

What do you get from `which -a guix`? Make sure you haven't installed
guix (the package) into a profile and are slowly making your way
backwards in time each time you reconfigure.

Hi Efraim,
thanks for helping me!
This is what I see when I run `which -a guix` as a user, and when run via
sudo. I do reconfigure the system with `sudo guix ...`. I used to as root. Not
sure if that matters.
[roman@m1 guix]$ which -a guix
/home/roman/.config/guix/current/bin/guix
/run/current-system/profile/bin/guix
/home/roman/.config/guix/current/bin/guix
/run/current-system/profile/bin/guix
[roman@m1 guix]$ sudo which -a guix
/home/roman/.config/guix/current/bin/guix
/run/current-system/profile/bin/guix
/home/roman/.config/guix/current/bin/guix
/run/current-system/profile/bin/guix
I have no idea if this is good or bad. :)
I don't think I have any `guix` package installed in my profiles. I checked
this with:
guix package -I | grep guix
sudo guix package -I | grep guix
Both profiles also seem to have a recent version of the `guix` cli.
[roman@m1 guix]$ guix --version
guix (GNU Guix) 68edde635d7f60fb48b2b664e55118fdc3021a73
[roman@m1 guix]$ sudo guix --version
guix (GNU Guix) 68edde635d7f60fb48b2b664e55118fdc3021a73
Was your thinking that I may got so far back in time somehow that the `guix`
package I was using did not contain the `efi-bootloader-chain` variable, and
thus `lookup-bootloader-by-name` could not find it?
Good idea, I haven't even thought of that. :)
But I think that's not the case here, isn't it?
Do you have any other ideas?
Thanks, Roman.

Hello,
I think I figured it out. In commit a9acbf919a7668e26863d2d26d48c5fd41b57fcd
the name of the efi-bootloader-chain bootloader was changed to the string
"efi-bootloader-chain". I believe this this should be a symbol, like in all
other bootloaders.
The `(lookup-bootloader-by-name name)` procedure uses this form
(eq? name (bootloader-name bootloader))
to find the bootloader by name, but fails. I submitted a patch that changes
the name of the efi-bootloader-chain bootloader to be a symbol. With this I
can roll-back and switch generations again on my system.
The patch is here:
https://lists.gnu.org/archive/html/guix-patches/2024-10/msg01009.html
I put Stefan on CC, who authored that commit.
Could someone please review this patch?
Thanks, Roman.
