I had the same problems when thinking about logrotation. What I don't like
in current schemes is that from distribution to distribution (and from one
UNIX to the other) configuring log rotation is different. RedHat has its
logrotate (which I do like very much), Debian has IMHO a slightly worse
solution. Providing these features in syslog-ng would make this
situation a bit easier. And strictly IMHO logrotation info should be kept
where log files are specified. (Debian does this, but it's too inflexible,
because I can't specify how many generations a given file should have, and
how often a given file should be rotated)

Maybe it would be enough to bundle a logrotation program with syslog-ng (for
example logrotate). Or simply file a wishlist bug for debian to move to
