Re: Devuan replaced grub and runs before Guix
Some clever developer from debian said me the easiest way. 1. I just enter grub command line while grub generated by Devuan appeared (with button 'c') 2. found grub.cfg on guix disk here: ls (hd0,gpt2)/boot/grub/grub.cfg 3. And used it to run grub with this menu config file like this: configfile (hd0,gpt2)/boot/grub/grub.cfg 4. Guix grub menu showed with its backgrund. And I booted to Guix OS 5. Then I just copied Guix menuentry from that grub.cfg file to my Devuan grub: # vim /etc/grub.d/40_custom: menuentry "GNU with Linux-Libre 5.13.13 (#33, 2021-09-04 17:57)" { search --file --set /gnu/store/y0dz7jdw78q3kgcjc8xy8zncxyl31k5p-linux-libre-5.13.13/bzImage linux /gnu/store/y0dz7jdw78q3kgcjc8xy8zncxyl31k5p-linux-libre-5.13.13/bzImage --root=/dev/sda2 --system=/var/guix/profiles/system-33-link --load=/var/guix/profiles/system-33-link/boot modprobe.blacklist=pcspkr,snd_pcsp,bluetooth,btusb,ath3k initrd /gnu/store/ccvhwm8h7h5xijab6gi65bjirz3nyxbv-raw-initrd/initrd.cpio.gz } # update-grub2 And now I sure boot to Guix from Devuan's grub menu entry. This is the easiest and may be reliable way. Just need to update grub menu entry when generate new system with 'guix system reconfigure config.scm'. Nice!

Oh heck, I used to manually kexec Guix, but it was on a different drive with its own GRUB install. /run/current-system seems to point to store entries ending in -system. So to find the store item: find /gnu/store -maxdepth 1 -name '*-system' Within the store item: kernel/bzImage: this is the kernel image to boot. initrd: this is the initramfs That should be enough info to build a GRUB menu entry. There are some other options like modprobe.blacklist but I'm not sure where they are in the store. Oh there is also the init binary. Uh. Not sure where that is. But I think this is a good enough starting point, hopefully you can figure out the rest. Alternatively, maybe try chrooting into the Guix partition and running reconfigure again? In any case, good luck!
How to reliably update Guix

Devuan replaced grub and runs before Guix
Hello, dear developers! Merry Christmas and Happy New year!I would like to ask questions I did not dug in the web, I hope there are short answers.I had Guix OS installed on /dev/sda and i had grub bootloader there configured to run guix and devuan from another sdd, my config:https://gitgud.io/youni/guix-configs/-/blob/master/config-wpa2-wlp5-wf-blacklist--my-desktop-services--isp.conf#L91Everything worked fine, i could boot to Guix or choose Devuan from the grub menu controlled by Guix.But i made Devuan 3 to Devuan 4 upgrades. And Devuan replaced grub and now i have no guix in the menu.I think i can add Guix to devuan grub menu, but I'm not sure I can find /vmlinuz and /initrd files in the Guix partitions.I have 3 questions:1. How to boot Guix manually from grub command line?2. How can I add Guix OS to devuan grub menu, which files i need to use for linux image and initrd, where to find them on Guix?3. Can I easy replace back grub by Guix making guix controls grub again?Thank you.
