Hmmm, I may be wrong, but I'd say that the log files are for
human debugging, and not for automatic test success checking.
For the latter we have exit codes And maybe messages to
What exactly makes it necessary to have the log of samba parsed
by the selftest system? We could also use the syslog thresold
to have low level debug msgs intercepted by the selftest system,
if this is strictly necessary...
Just my 2cents...
