I’m trying to switch from openrc to systemd on my gentoo-desktop (don’t ask why).

It’s starts easy:

• changing profile from desktop/plasma to dektop/plasma/systemd.
• Then everything reemerge world -uDtvaN …
• Compiling new kernel with appropriate settings.
• creating a new initramfs with dracut --kver <kernel-version>
• rebooting

Now it become complicated:

Systemd stucks in boot when it fails to mount zfs and switching root to the new base. After a long journey I found a workaround:

• omit dracut-module systemd
• adding init=/usr/lib/systemd/systemd as a kernel-parameter in grub.
