Subject: [PATCH] logrotate: better rotation options
The extant "logrotate_daily" varaible doesn't really do anything and
isn't used. Modify this to be able to set a range of rotation periods
or a size.
Update mirror rsync mirrors to rotate weekly, as often releases run
overnight and it's a pain to reconstruct.
