Wow, that message is shown when I check UPDATING after latest csup to STABLE.

20090207:
Multi-IPv4/v6/no-IP jail support was merged to STABLE.
You need to rebuild jls(8) and to use the new features
jail(8), jexec(8) and cpuset(1) with a new kernel.
__FreeBSD_version was bumped to 701103.

Try to do that :

# cd /usr/src/usr.sbin/jls/

# make clean && make depend && make && make install
rm -f jls jls.o jls.8.gz jls.8.cat.gz
rm -f .depend
mkdep -f .depend -a    -DSUPPORT_OLD_XPRISON /usr/src/usr.sbin/jls/jls.c

I see, I’ll need new kernel icon smile You need to rebuild jls(8) and to use the new features jail(8), jexec(8) and cpuset(1) with a new kernel
