[syslog-ng]logs getting stomped on

[Brian Landers]

Well, it turns out my log file truncation problems were due to the
nightly system backups.  Other than running the agent, I have zero
interaction with the backups, so they're easy to forget.  Apparently.
Backup Exec's UNIX agent was trying to backup the log file and was
truncating it somehow (not sure how it's pulling that one off).

I've added the log dir to the excludes for the backups and the file
is no longer being truncated.

Cheers,
