Comment 3 for bug 1130611

 · Because upstart opened it.
 · Because it has closed all the others in /var/log/upstart except that one.
 · Which makes it look like there's some reason this particular one is "special".
 · I haven't added anything to anything.
 · ... sure, it's probably an issue that whatever is rotating the logs needs to restart init, but _why_ is the file descriptor still open, when the mysql service has been up for more than two days?
 · This could, for all I know, be a bug in the mysql service config file. I'm just reporting the oddity that this one log file seems to have been left open.
