>Description:
By default (/usr/src/etc/crontab) /etc/daily is run every night.
By default (/etc/defaults/daily.conf) /etc/daily runs /etc/security.
By default (/etc/defaults/security.conf) /etc/security runs check_passwd
with check_passwd_permit_nonalpha=NO.

With the introduction of '_pflogd' (and presumably others to follow),
/etc/security starts to complain nightly:

Checking the /etc/master.passwd file:
Login _pflogd has non-alphanumeric characters.

Checking the /etc/group file:
Group _pflogd has non-alphanumeric characters.

I doubt the system should warn nightly about consistent, intended
settings. This also reduces usefulnes of /etc/security checks.

>How-To-Repeat:
Install NetBSD-current and observe nightly warnings about non-alphanumeric
characters in uid/gid names.
>Fix:
Make /etc/security know about special system accounts using '_' as
first character.
