Hello Lars,
not sure about the OS you're using, probably FreeBSD (?), but you will
have to re-create the device nodes in the MFS partition under /dev after
setting up the MFS. Mounting stuff in memory is more complex than just
editing fstab.. Best done from a script from /etc/rc{whatever}. For an
OpenBSD example see these:

Good luck with it,
Bill
