If you look at the FreeBSD /etc/passwd, sure, but this is an OpenBSD
convention.  Looking at the OpenBSD src/etc/master.passwd[1], it's very
consistently used, with the few system UIDs not starting with an =
underscore
being either legacy names or tied to a third-party package (sendmail, =
BIND,
popa3d).
