Back in summer, I wrote a short, short little perl script for setting up a bunch of FreeBSD jail environments using a single base directory from which each jail would access via read-only nullfs mounts within each jail. This web site is running inside just such a jail environment.

I've since used the script on my personal server and at work where it has proved very useful.

Like much of my computer geek stuff, it comes with little-to-no documentation other than the comments in the script itself and also those on the web page I made for it.

The web page is here:I'd intended to post this in September, so the web page has been available for over four months, but without any links to it. This post should remedy that.

UPDATE: 13 June 2007

Since I originally posted this, I've been converted to ezjail from the FreeBSD ports collection. It does much, much more than my script. Very useful!

Thanks, Dirk Engling!
