I started using Gentoo in the 1.4 days.  I to changed /dev/ROOT to
/dev/root and added the proper locations/options for root and every
other mount point I have.  This is the first I have heard of fstab not
needing the root mount line.  If this is a change, someone needs to tell
the users, even us old timers.  ;-)
