Hi guixers,
I want to dualboot into GuixSD. My main os is currently NixOS.
Currently, I don't want to let guixsd control my grub setup. So my
situation is similar to [1].
One solution is to use the unreliable chainloading with blocklists by
invoking grub-install --force /dev/sda3 after every guix system
reconfigure config.scm. (The config.scm has sda3 as grub target.)
The second (and IMHO the right) solution I am aware of is adding the
following in the grub.cfg which is handled by nix:
menuentry "GuixSD - Configloader" {
configfile (hd0,gpt3)/boot/grub/grub.cfg
}
This way, grub loads the newest grub config file created from GuixSD.
There is only a minor annoyance:
guix system reconfigure config.scm returns non-zero and spits out an
error (because grub-install wants --force to use blocklists). But it
succeeds in everything else, especially in creating a new
/boot/grub/grub.cfg.
The alternative (guix system reconfigure --no-bootloader config.scm)
doesn't update /boot/grub/grub.cfg.
I'd like to have a way to have /boot/grub/grub.cfg updated without
reinstalling grub on the disk/partition and without having a command
return non-zero.
This could be done by adding a cli argument for reconfigure or allowing
an empty string in (grub-configuration (target "")).
WDYT?
