I've just installed a #FreeBSD jail using #bastillebsd in less than 30' using @6107fbe2's article :

 This nice little thing is using #zfs datasets to save space, uses only 5 meg after creation. 

After that, 'bastille console' chroots you into it, and it's 10 min to setup root/user & ssh.

The syntax is intuitive, everything is well thought out, I'm impressed.
