1. What user logrotate is normally run as?
2. Does logrotate really need to connect to mysqld do issue "FLUSH"?
Why not send SIGHUP instead? This needs no user and no password.

I don't have logrotate installed locally, so I've googled for "man logrotate",
and the man page said it's "sharedscripts", not "shared". Why did you
have "shared" - different logrotate version?
I have no opinion on "daily" vs "weekly" and "rotate 3" vs "4".

Right, good idea.
