+Streamline Userland Installation On FreeBSD Jails Using SysinstallPosted
+by: admin  :  Category: jails
+There is probably a dozen of ways to install the userland for use within
+a FreeBSD jail.
+
+Most of the documentation I saw (including the man page itself) refers
+to building/installing from the source tree. Sysinstall seems only to be
+considered for additional post-configuration tasks and is always run
+inside of the jail.
+
+While building/installing a jail may have it’s advantages in respect to
+security flaws or bugs in general, installing through sysinstall may be
+faster and probably less error prone.
+
+It is in fact very easy to run sysinstall in non-interactive mode on the
+host itself (not inside the jail!) from a shell script, which may
+optionally run some post-installation tasks afterwards.
+By the fact that sysinstall can use the same command line arguments as
+if given through a configuration file, a single line could be used in
+your script to achieve this:
+
+# sysinstall nonInteractive=yes \
+_ftpPath=ftp://ftp2.ch.freebsd.org/pub/FreeBSD \
+mediaSetFTP distSetMinimum installRoot=/var/jails/192.168.0.1 \
+releaseName=6.1-RELEASE installCommit
+
+This line would cause sysinstall to run in non-interactive mode, useing
+ftp://ftp2.ch.freebsd.org/pub/FreeBSD as it’s download source.
+DistSetMinimum selects the smallest userland possible while installRoot
+is given to define destination directory.
+
+releaseName ist required to choose the actual release and must be set to
+your main release (e.g. 6.0-RELEASE, 6.1-RELEASE, etc). If you don’t set
+it, sysinstall will use the release name of your currently installed
+userland (e.g. 6.1-RELEASE-p1) and will most definitly fail because
+there exists no such distribution set for download.
+It is also possible to choose a different release like 5.5-RELEASE to be
+installed inside a jail. You must consider though that most tools will
+run expect those that interact with the kernel directly (ps, top, etc).
+In generall I would not recommend mixing releases expect you have a very
+good reason to do so.
+
+Don’t forget to add the installCommit command at the end otherwise
+sysinstall won’t do anything at all.
+
+By examing the sysinstall man page you will find other options to select
+different (or build customer) dist sets.
