Generally, yes, although we'd need to consider any deviations away
from our new general policy of
	``namespace protecting per service user (and group) names
	with a leading `_' to prevent nameclashes with user accounts
	on end user systems.''

  |  * should all "system" accounts be renamed to have a leading "_"?

Yes, for the appropriate system accounts (not necessary `all "system"
accounts').  These would include accounts we've added recently
for specific services (sshd, smmsp, ntpd, named) except where that
would break the common usage for that service and it makes sense.

We need to consider the migration plan for these accounts.
Some proposals have been suggested:

    *	Update postinstall to warn about this.
	However, not fix, for the same reason we don't for
	the existing uid/gid checks: the user accounts
	may actually be in a separate (nsswitch) passwd
	database than /etc/master.passwd.
	postinstall could be updated to try getent, but
	that could only work for 'native' invocations,
	not cross or destdir invocations.

    *	Add replicate entries for the accounts we're renaming,
	leaving the old account and the new one, at least
	for a release.
	That will cause /etc/security to complain.

Because of the complexity of the migration decision, core decided
to keep separate the operations of changing the per-service username
policy and using that for pflogd from the operation of renaming
existing accounts.


(Speaking personally, providing background on the core decision).
