[ATrpms-users] log-rotate facility for mythtv

[Jeffrey J. Kosowsky]

Well, you guys are both right that there is already a logrotate
facility for mythbackend -- I had not thought to look because I never
saw it rotate.
The problem is that it has the parameter size=10M.
Why don't we just comment that out, then we should get weekly rotates
similar to other log files?

Axel, I agree that in these days of near terabyte disks and HD-quality
streams, that 10M is not a lot. On the other hand, as a matter of
'clean' Linux/Unix programming principles (vs. Microsoft bloatware),
there is no reason to have multi-megabyte log files.

In fact, the primary reason that I suggested a weekly rotate, is that
when debugging using the mythbackend log, I had to page through nearly
a megabyte of text dating back to October which was a pain in the
neck. I can't imagine ever needing more than a week of log files (plus
4 other weeks of backups) to debug anything...
