Trivial patch for FreeBSD's /etc/rc.d/jail to add support
for mac_partition(4) partitions.
It introduces a new per-jail variable in rc.conf(5), similar
to the _fib variable used by setfib(1).
/etc/rc.conf:
jail_enable="YES"
jail_list="foobar"
...
jail_foobar_partition="42"
...
This will prepend the call to jail(8) with setpmac partition/42.
Note:
- this does not add any restrictions to the jail that the jail system does not already impose on its own. It only adds another layer and maybe a warm fuzzy feeling
- since you can not set partitions inside a jail, setting a partition for the entire jail is no loss in functionality
- you can use
kldstat -q -m mac_partition; echo $?to check if the mac partition module is loaded / compiled into your kernel - this patch was originally made against FreeBSD 8.3, it can easily be adopted to FreeBSD 9.x if you use the "old" jail configuration style
- FreeBSD 10 jail.conf(5) configuration is not supported. If you know a way, let me know
Various patches against FreeBSD 10.0-RELEASE-p7 to accomplish stuff can be found in the fbsd10/ directory. Check to commitlog of the files for descriptions etc.
