Ah, OK.  I was just assuming GNU/Linux and was surprised that some 
distro wasn't using some log rotator.  Hadn't even heard of newsyslog 
(and had I, I would have assumed it was another 
syslog/syslog-ng/rsyslog/... implementation versus a log rotator :).

Definitely true.  And, if you're using sane logging/verbose levels (such 
as the defaults), you won't get that much log output from MythTV (at 
least not compared to disk sizes)--unless you have really bad video (bad 
reception or whatever) and ffmpeg complains about every bit of it...
