To prevent guix gc from removing *grub.cfg file under /gnu/store/

Hi Guix!

Since my BIOS comes with in-built grub payload, I did not want to install bootloader on disk (but do want grub.cfg file under /gnu/store/), so I passed --no-bootloader parameter during guix system init. The guix system got successfully installed and there was *grub.cfg file under /gnu/store/. The file stayed even after multiple reboot, guix pull and guix package -u. But when I did guix gc, it removed the *grub.cfg file under /gnu/store/. How can I prevent this from happening?

I thought of using "guix build [...] --root=" command, but the file "*grub.cfg" under /gnu/store/ is created by the system (not user) during "guix system init" process. So how can I prevent "guix gc" process from removing a system created file?

Since I am a novice user, please provide me a step-wise explanation. Also, I have posted the same issue at "guix-devel" ML. If you are an admin seeing this post, kindly do not close this post as repeat, as there are different individuals subscribed to these MLs.

Thank you!

Regards,
RG.

Hi Raghav,

You can prevent this behaviour if you don't pass "--no-bootloader", and
use in your config.scm the code snippet I showed you in a previous
email, so that GRUB isn't installed.

Hi Clement!

I wanted to contact you but I lost your email ID. Yes, the code snippet you gave me did work perfectly. I just tested it today. Thanks a lot.

Regards,
RG.
