i did.  and the source.  netbsd says it's for storing the domainname,
with no particular indication of why or wherefore.  other systems (eg
solaris) use it for nis.  i'm very much in favor of homogeneity, so
i'm not about to go storing something in somewhere which some systems
use for nix and some don't.  i'll find a way that works the same way
on all machines.  netbsd's nis was written "to be compatible with
Sun's implementation".  i'd be surprised if it didn't use the kernel
info (modulo it simply being told not to).

under netbsd it doesn't have a special purpose.  saying it's for mail
is just as wrong as anything else.
