.SH DESCRIPTION
\fBsbuild\-update\fR runs \f[CB]apt\-get\fP inside the specified chroot
performing \f[CB]update\fP, \f[CB]upgrade\fP, \f[CB]dist\-upgrade\fP,
\f[CB]clean\fP, \f[CB]autoclean\fP, and/or \f[CB]autoremove\fP depending on the
options specified on the command line.
.PP
\fBsbuild\-upgrade\fR, \fBsbuild\-distupgrade\fR, and \fBsbuild\-clean\fR, are
deprecated. They now simply run \fBsbuild\-update\fR with the appropriate
options (\f[CB]\-\-upgrade\fP or \f[CB]\-\-dist\-upgrade\fP for
\fBsbuild\-upgrade\fR or \fBsbuild\-distupgrade\fR respectively) along with
whatever arguments were passed in the scripts.

.SS Chroot selection
.TP
.BR \-\-chroot-mode=\fIschroot|sudo|unshare\fP
The sbuild chroot backend of the chroot to update. The autopkgtest backend is
not supported by this method because autopkgtest backends are always ephemeral
and changes never persist. To update a chroot for schroot and sudo,
sbuild-update must be executed with superuser privileges (for example by using
sudo). Creating a chroot for the unshare backend can be done by a normal user
(without sudo) but it requires Linux user namespaces to be enabled (via "sysctl
-w kernel.unprivileged_userns_clone=1"). Defaults to 'schroot'.
.TP
.B CHROOT
The chroot to use. Note that \[oq]o\[cq], \[oq]s\[cq],
\[oq]t\[cq], \[oq]u\[cq] and \[oq]e\[cq] may be used as abbreviations for
\[oq]oldstable\[cq], \[oq]stable\[cq], \[oq]testing\[cq], \[oq]unstable\[cq]
and \[oq]experimental\[cq], respectively.
.SH EXAMPLES
To update the \fIunstable\fP chroot:
.PP
\f[CR]% \f[CB]sbuild\-update \-\-update unstable\fP\fP
.PP
To upgrade the \fIunstable\fP chroot:
.PP
\f[CR]% \f[CB]sbuild\-update \-\-upgrade unstable\fP\fP
.PP
To clean the \fIunstable\fP chroot:
.PP
\f[CR]% \f[CB]sbuild\-update \-\-clean unstable\fP\fP
.PP
To perform an update, dist-upgrade, clean, autoclean, and autoremove for
the \fIunstable\fP chroot:
