Martin, the issue here is that starting a jail with a recent -current
panics, if the jail has a dataset assigned to it during start (and
the rc.d zfs scripts kicks in). At least in my case the jail contains an
userland from before the change and the jail host a current userland.
Any ideas / suggestions? pho@ has a test case for this.
