Bastille create uses any available bootstrapped release to create a lightweight jailed system. To create a jail simply provide a name, bootstrapped release and a private (rfc1918) IP address.
ishmael ~ # bastille create folsom 11.2-RELEASE 10.8.62.1 RELEASE: 11.2-RELEASE. NAME: folsom. IP: 10.8.62.1.
This command will create a 11.2-RELEASE jail assigning the 10.8.62.1 ip address to the new system.
I recommend using private (rfc1918) ip address ranges for your jails. These ranges include:
Bastille does its best to validate the submitted ip is valid. This has not been thouroughly tested–I generally use the 10/8 range.
