It might be safe, but there is no compelling reason to run it as root,
and a common sense advises against it. Even if it needs to bind
to a low port number, haproxy is capable of dropping privilege after
binding to a socket, and continues running under some other uid/gid,
Apparently there isn't any standard FreeBSD uid assigned for
this purpose. Either make up one, or it may be good enough
to re-use one of the existing ones, perhaps the www account.
Perhaps the haproxy port maintainer can be persuaded to assign
some account entry for this purpose.
