From 65fd72d76d37cd0045671ac54369cf5e5d144ec5 Mon Sep 17 00:00:00 2001
From: Martin Schwenke <martin@meltin.net>

Subject: Add base file /root/scripts/functions.  setup_samba.sh now properly
 waits for a completely healthy cluster.  chroot jail generation goes after
 winbind start.  We also no longer try to fix the jail - assume a working
 cnjailgen is hacked in via some other process.
