Well technically, we used (and still use, see below) the uppercase 
/dev/ROOT, with instructions documenting what to replace it with.  But 
some users apparently simply lowercased that ROOT, and for years it "just 
worked". (Below output edited slightly for posting. $>> indicates the 
shell prompt.):

[TLDR folks can stop there.  The rest is historic observation, arguably 
interesting, admittedly ranty, but not vital.]

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 /supposed/ to have it simply 
overwritten.


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.  ;-)
