I posted here because I was having a problem with Calibre, and I heard the maintainer was very helpful.
Then I found a workaround, and posted an update. The workaround needs to be applied to every version of Linux (Fedora, Ubuntu, Debian, Suse) that uses automounting. So I posted information on that too.
I also posted this to the Fedora bugzilla, but that won't really help since it's a problem that needs solving in calibre.
