Subject: [PATCH] lvm: do not run pvscan for lvmetad update
The lvmetad daemon is not yet running in initramfs so there's no
need to run pvscan (or instantiate any lvm2-pvscan systemd service).
If pvscan was called in this case (either directly or via systemd
instantiated service), it would fail because there's no lvmetad
daemon to update. This could cause confusion, especially in systemd
instantiated service which is run only once!
