libutil is for stuff that is used commonly in a wide variety of system
daemons in abstracting system related functions. "spawn a login
shell", "get a pty and modify the utmp entry", and such are very very
much libutil sorts of things.

libc is for stuff of *general* use to a programmer, even if they're
not dealing with system related goo. "humanize_number" is very much
not a libutil thing -- same for fparseln. Both could be used in almost
any sort of program.

libutil is for system utilities -- util does not refer to the contents
of the library but to the clients of the library.
