These are init scripts for the Gentoo-maintained OpenRC init system, not 
what ships with samba. Here's a complete set of messages from a clean 
start (without unix extensions enabled):

and with unix extension enabled:

Well, hmm, this time it doesn't crash. The *only* change on the AD I 
made was to uncomment the "unix extensions = yes" line in smb.conf.
