Under that logic, *none* of the names in common use are absolute 
(example.com should really be example.com.).  The search algorithm for 
non-rooted pathnames is considered system-specific, but a non-rooted 
FQDN is obviously expected to work.  There has been a very small number 
of valid single-stanza FQDNs ("va" was valid for a while), but they are 
few and far between, and you can deal with them by adding a dot - "va."

So I think what you have is perfectly fine for a boot loader, certainly.
