description:
Draft man pages for the standard users and groups.
These are currently listed in order of uid because I went through
src/etc/group and src/etc/master.passwd line by line, and sorting any
other way after the fact -- like lexicographically, how it should be
-- was kinda inconvenient.
Feel free to sort, add information, add historical references,
correct any mistakes, &c., so that these remain living documents
describing NetBSD's standard users and groups and practices around
them.

+.Sh DESCRIPTION
+A standard
+.Nx
+installation has the following user group names:
+.\" These are currently sorted by gid; perhaps they should be sorted
+.\" lexicographically by name instead.
+.Bl -tag -width "_tcpdump"
+.It Em wheel
+Users authorized to elevate themselves to the super-user privileges of
+the root user, meaning uid 0.
+Normally the
+.Em wheel
+group has gid 0.
+.Pp
+Users who are not in the group
+.Em wheel
+are never allowed by
+.Xr su 8
+to gain root privileges.
+.It Em daemon
+Used by the set-group-id
+.Pq Xr setuid 7
+programs
+.Xr lpq 8 ,
+.Xr lpr 8 ,
+and
+.Xr lprm 8 .
+.\" Unclear why. Maybe used to be used by uucp stuff too, since
+.\" /var/spool/lock ownership is uucp:daemon?
+.It Em sys
+Historic group.
+Unused in modern
+.Nx .
+.It Em tty
+Used by the set-group-id
+.Pq Xr setuid 7
+programs
+.Xr wall 8
+and
+.Xr write 1
+to allow users to send messages to another tty even if they don't own
+it.
+Static tty device nodes in
+.Pa /dev
+are all in the group
+.Em tty ,
+and the
+.Xr mount_ptyfs 8
+program passes the gid of the
+.Em tty
+group to the kernel so that all nodes in
+.Pa /dev/pts
+or equivalent are in the group too.
+.It Em operator
+Users authorized to take backups of disk devices and shut down the
+machine.
+.Pp
+The disk device nodes in
+.Pa /dev
+such as
+.Pa /dev/rwd0a
+are in the group
+.Em operator
+and group-readable so users in the group can read from disk devices,
+for example with
+.Xr dump 8 .
+The tape device nodes in
+.Pa /dev
+such as
+.Pa /dev/rst0
+are in the group
+.Em operator
+and are both group-readable and group-writable so users in the group
+can write to tape devices.
+.Pp
+The
+.Xr shutdown 8
+program is executable only by root and members of the
+.Em operator
+group.
+.It Em mail
+Historic group.
+Unused in modern
+.Nx .
+.\" Is this true? Hard to grep for this in src...
+.It Em bin
+Historic group.
+Unused in modern
+.Nx .
+.It Em wsrc
+Historic group.
+Unused in modern
+.Nx .
+.\" Actually it seems to be used in the set lists somehow, but it's
+ \" unclear to me how what the significance is.
+.It Em maildrop
+Used by the set-group-id
+.Pq Xr setuid 7
+programs
+.Xr postdrop 8
+and
+.Xr postqueue 8
+to submit to and examine the
+.Xr postfix 8
+mail queue at
+.Pa /var/spool/postfix/maildrop
+and
+.Pa /var/spool/postfix/public .
+.It Em postfix
+Primary group for the
+.Em postfix
+pseudo-user used by the
+.Xr postfix 8
+mail transfer agent.
+.\" Why are various subdirectories of /var/spool/postfix owned by
+.\" postfix:wheel and not postfix:postfix?
+.It Em games
+Used by various set-group-id
+.Pq Xr setuid 7
+games to maintain high-scores files and other common files in
+.Pa /var/games .
+.It Em named
+Primary group for the
+.Em named
+pseudo-user used by the
+.Xr named 8
+DNS nameserver daemon.
+.It Em ntpd
+Primary group for the
+.Em named
+pseudo-user used by the
+.Xr ntpd 8
+network time protocol daemon.
+.It Em sshd
+Primary group for the
+.Em sshd
+pseudo-user used by the
+.Xr sshd 8
+secure shell daemon.
+.It Em _pflogd
+Primary group for the
+.Em _pflogd
+pseudo-user used by the
+.Xr pflogd 8
+log daemon with the
+.Xr pf 4
+packet filter.
+.It Em _rwhod
+Primary group for the
+.Em _rwhod
+pseudo-user used by the
+.Xr rwhod 8
+system status daemon.
+.It Em staff
+Staff users, in contrast to regular or guest users.
+Not used by
+.Nx ;
+available for the administrator's interpretation.
+.It Em _proxy
+Primary group for the
+.Em _proxy
+pseudo-user used by the
+.Xr ftp-proxy 8
+and
+.Xr tftp-proxy 8
+proxy daemons with packet filters such as
+.Xr pf 4
+or
+.Xr ipnat 4 .
+.It Em _timedc
+Primary group for the
+.Em _timedc
+pseudo-user used by the
+.Xr timedc 8
+tool to communicate with the
+.Xr timed 8
+time server daemon.
+.It Em _sdpd
+Primary group for the
+.Em _sdpd
+pseudo-user used by the
