If you swap the hdd from one system to another it doesn't suddenly start
requiring raid support or need lvm. What can be a problem is suddenly
missing the right module for the controler so no disk is found.
This is something you already have for /. Including "mount /usr" in the
initramfs in no way changes this. And default is, as Reinhard says, to
build a big initramfs with lots of modules in there just in case.
