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. ;-)

Years ago (remember, my first successful gentoo install was 2004.1), the
fstab example file found in /usr/share/baselayout/fstab was packaged as
/etc/fstab directly. Now, the handbook of the era took great pains to
guide people thru editing it appropriately, saying the ALLCAPS entries
were intended to be replaced as appropriate for the individual install,
AND people were expected to actually use etc-update or the like for its
intended purpose, so people weren't <i class="moz-txt-slash"><span class="moz-txt-tag">/</span>supposed<span class="moz-txt-tag">/</span></i> to have it simply
