.TH postroot 1
.SH NAME
postroot, tun \- share a terminal's root file system
.SH SYNOPSIS
.B postroot
.PP
.B tun
.I target
.SH DESCRIPTION
.PP
When connected to a cpu server via
.IR cpu (1),
.I postroot
posts a terminal's root file system on the cpu server.
This is particularly useful with
.IR drawterm (8)
or
.I tun
(see below). The posted file will be named in the pattern
.IR user . terminal-name .postroot.
.PP
.I Tun
will mount
.BI /srv/ target
and bind its
.B /net
onto
.B /net.alt
in the current namespace, then
.IR cpu (1)
to the target using that interface. The intended use is
in conjunction with
.I postroot
to circumvent firewalls.
