Assuing the kernel has anything required to start up built in (i.e., no modules are required to boot, mount the root, switch root, or mount any volumes described in /etc/fstab, access any resources used for anything started via openrc or systemd), lvm.conf includes "use_lvmetad = 1" in both the initrd and vg00/root.
I've tried tracing the logic produced by dracut to see why it failed, but at over 1000 lines I do not have time to verify its logic and see where it failed; ditto genkernel: there is too much logic to ignore checking modules that don't exist because they are in the kernel. Looking at: <https://wiki.gentoo.org/wiki/Systemd> I've verified that the options are set (including choosing systemd as the init), /run is there, /mtab is what is should be, GRUB is updated. The example below works perfectly with openrc, fails with systemd (along with dracut results). Q: What are the minimum steps/configuration required to set up and switch_root to systemd? thanks #!/bin/busybox sh root='/mnt/root'; init='/sbin/init'; /bin/busybox --install -s; mount /sys; mount /proc; lvm vgscan -v; lvm vgchange -v -a y; mount /dev/vg00/root $root; for i in $root/$init $root/usr $root/usr/bin do # drop to shell if the root filesystem is botched.
