Reason: mostly just for fun, but I also believed it might be better to use systemd whenever possible to not mix too many different approaches.
Unfortunately (after re-generating grub and mkinitcpio of course) system became unbootable. I had to chroot and remove the changes to get bootable system again.
Anyone has any idea what I made wrong?
I followed this list: https://wiki.archlinux.org/index.php/Mkinitcpio#Common_hooks
Also my understanding and I missed the first. Will try soon.
Btw: I have 2 kernels, linux and linux-zen. If I do the changes to grub and mkinitcpio and then only do mkinitcpio -p linux
(and not for linux-zen) as well as grub-mkconfig -o /boot/grub/grub.cfg
(Question again: is sequence important to do mkinitcpio command first?)
Should I then still be able to boot with linux-zen kernel?
