.TH NEWUSER 8
.SH NAME
newuser \- adding a new user
.SH SYNOPSIS
.B /sys/lib/newuser
.SH DESCRIPTION
To create a new user on Plan 9, add the user to
.IR fossil (4)
with the
.B uname
command and create
.BR /mail/box/$user
to hold the user's mailbox
with the
.B create
command (see
.IR fossilcons(8)).
Next, give the user a password using
.B auth/changeuser
on the console of the authentication server (see
.IR auth (8)).
At this point, the user can bootstrap a terminal using the new name and
password.
The terminal will only get as far as running
.BR rc ,
however, as no
.B profile
exists for the user.
.PP
The
.IR rc (1)
script
.B /sys/lib/newuser
sets up a sensible environment for a new user of Plan 9.
Once the terminal is running
.BR rc ,
type
.IP
.EX
/sys/lib/newuser
.EE
.PP
to build the necessary directories in
.B /usr/$user,
create
.BR /mail/box/$user/mbox,
.BR /cron/$user/cron,
a reasonable initial profile in
.BR /usr/$user/lib/profile
and
plumbing rules in
.BR /usr/$user/lib/plumbing
(see
.IR plumber (4)).
The script then runs the profile which, as its last step, brings up
.IR rio (1).
At this point the user's environment is established and running.
There is no need to reboot.
It may be prudent at this point to run
.IR passwd (1)
to change the password, depending on how the initial password was chosen.
.PP
The
.B profile
built by
.B /sys/lib/newuser
looks like this:
.IP
.EX
bind -a $home/bin/rc /bin
bind -a $home/bin/$cputype /bin
bind -c tmp /tmp
font = /lib/font/bit/pelm/euro.9.font
switch($service){
case terminal
	plumber
	upas/fs
	echo -n accelerated > '#m/mousectl'
	echo -n 'res 3' > '#m/mousectl'
	prompt=('term% ' '	')
	fn term%{ $* }
	exec rio
case cpu
	if (test -e /mnt/term/mnt/wsys) {
		# rio already running
		wsys = /mnt/term^`{cat /mnt/term/env/wsys}
		bind -a /mnt/term/mnt/wsys /dev
		echo -n $sysname > /dev/label
	}
	bind /mnt/term/dev/cons /dev/cons
	bind /mnt/term/dev/consctl /dev/consctl
	bind -a /mnt/term/dev /dev
	prompt=('cpu% ' '	')
	fn cpu%{ $* }
	upas/fs
	news
	if (! test -e /mnt/term/mnt/wsys) {
		# cpu call from drawterm
		font=/lib/font/bit/pelm/latin1.8.font
		auth/factotum
		plumber
		exec rio
	}
case con
	prompt=('cpu% ' '	')
	news
}

Sites may make changes to
.B /sys/lib/newuser
that reflect the properties of the local environment.
