Command: sudo eggs dad -d Produces on fresh install of penguins-eggs output:

Daddy, what else did you leave for me?
- creating configuration dir...
Due the lacks of calamares package set force_installer = false
/_active/rootvol/boot/vmlinuz-linux not exists!

contents of boot directory, where vmlinuz-linux is found:

ls /boot
efi  grub  initramfs-linux-fallback.img  initramfs-linux.img  intel-ucode.img  syslinux  vmlinuz-linux

I think the issue is that the parsing for location of vmlinuz-linux doesn't understand the btrfs subvolume setup, where /dev/sda3 contains _active and _snapshots subvolumes and /_active/rootvol subvolume in /dev/sda3 is mounted to / -directory. Instead it tries to find _active from under the filesystem / -directory, which obviously doesn't exist.

The idea of this setup is that all snapshots of subvolumes are available under /_snapshots in /dev/sda3 and the snapshotted files can then be accessed through /mnt/defvol, where the /dev/sda3 is mounted.

orion% ls /mnt/defvol
_active  _snapshots
orion% ls /mnt/defvol/_active
homevol  rootvol
orion% ls /mnt/defvol/_active/rootvol
bin  boot  dev  etc  home  lib  lib64  mnt  opt  proc  root  run  sbin  srv  sys  tmp  usr  var

I think it should figure out that subvol=/_active/rootvol of /dev/sda3 is mounted to / and be able to remove the /_active/rootvol from the attempted path somehow.

Hi Apocalyt you're probably right, I'm not too familiar with btrfs, anyway this is the code that retrieve vmlinuz, I hope you can give me some suggestions.

Thanks
