NEWUSER(8) NEWUSER(8)
NAME
newuser - adding a new user
SYNOPSIS
/sys/lib/newuser
DESCRIPTION
To establish a new user on Plan 9, add the user to
/adm/users by running the uname command on the console of
the file server (see users(6)). Next, give the user a pass-
word using auth/changeuser on the console of the authentica-
tion server (see auth(8)). At this point, the user can boot-
strap a terminal using the new name and password. The ter-
minal will only get as far as running rc, however, as no
profile exists for the user.
The rc(1) script /sys/lib/newuser sets up a sensible envi-
ronment for a new user of Plan 9. Once the terminal is run-
ning rc, type
/sys/lib/newuser
to build the necessary directories in /usr/$user, create
/mail/box/$user/mbox, /cron/$user/cron, a reasonable initial
profile in /usr/$user/lib/profile and plumbing rules in
/usr/$user/lib/plumbing (see plumber(4)). The script then
runs the profile which, as its last step, brings up rio(1).
At this point the user's environment is established and run-
ning. (There is no need to reboot.) It may be prudent at
this point to run passwd(1) to change the password, depend-
ing on how the initial password was chosen.
The profile built by /sys/lib/newuser looks like this:
bind -a $home/bin/rc /bin
bind -a $home/bin/$cputype /bin
bind -c tmp /tmp
font = /lib/font/bit/pelm/euro.9.font

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