FWIW, Solaris2 does it with (if I recall correctly):

/usr/lib/fs/<fstype>/<fstype><progname>

so ufsdump is /usr/lib/fs/ufs/ufsdump and ufsrestore is
/usr/lib/fs/ufs/ufsrestore.

(but you might have symbolic links to it from elsewhere, say
 /usr/sbin/ufsdump).

Obviously there are easily observed advantages to organising these
programs in such a manner, as opposed to using a single directory
(i.e. /sbin).  Also, in consideration for keeping / size down, it
maybe desirable to consider subdirectories under /usr. 

Whether it is mount_msdos or msdos_mount, it doesn't matter.  That we
now have mount_* suggests that this trend be followed rather than break
with it and make an adhoc change which will cause user problems and
achieve nothing more than pleasing some peoples sense of asthetics.

If there is a desire to have things organised by directory, then by all
means do so, put make sure symbolic links are used, to save path length
and existing PATH settings (if nothing else).

p.s. I moved it to current-users as this isn't i386 specific.
