Create a Debian Squeeze jail (GNU/kFreeBSD)

In this howto we will set up a Debian (GNU/kFreeBSD) jail. GNrUkFreeBSD is a Debian userland tailored for the FreeBSD kernel.

Don’t forget to replace UUID with your jail’s full UUID!

Create an empty jail with linux specifics:

iocell create -e tag=debian exec_start="/etc/init.d/rc 3" exec_stop="/etc/init.d/rc 0"

Install debootstrap on the host:

pkg install debootstrap

Grab the mountpoint for our empty jail, append /root/ to it and run debootstrap:

iocell get mountpoint UUID | TAG

debootstrap squeeze /iocell/jails/UUID/root/ (you can replace squeeze with wheezy if that is what you need)

Edit the jail’s fstab and add these lines:


linsys   /iocell/jails/UUID/root/sys         linsysfs  rw          0 0
linproc  /iocell/jails/UUID/root/proc        linprocfs rw          0 0
tmpfs    /iocell/jails/UUID/root/lib/init/rw tmpfs     rw,mode=777 0 0

Start the jail and attach to it:

iocell start UUID | TAG

iocell console UUID | TAG

What you gain is a 64bit Debian Linux userland. Please note this is not recommended for production use. The intention was to show that iocell will let you do almost anything you want with your jails.
