"# mkinitcpio -p linux" fails to build the default image when I have a specific FUSE filesystem mounted. The failure happens with the default HOOKS and with the customized HOOKS that I usually use. have attached a log that shows the failure.

The FUSE filesystem that causes the error when mounted is a just a little project that I thew together:
<https://github.com/ooesili/flac-fs>
but that is not really important. The reason mkinitcpio fails is because of the information that the filesystem displays with the "findmnt" utility. When mounted, the line returned from "findmnt" says the the SOURCE is "/", and the FSTYPE is "fuse./". The autodetect install-hook uses the command "$(find -uno fstype '/')" to determine the type of the root filesystem. When my FUSE filesystem is mounted, that command returns "fuse./", because findmnt searches the SOURCE column for matches before searching the TARGET column. I've included a patch that fixes this issue.

If you wish to repoduce the bug, you can download and make my project, and mount it anywhere, but you have to use an absolute path for the first argument, so that the SOURCE column under findmnt displays '/'.

Now, you may be thinking that this is a bug with my project, or FUSE, but any filesystem mount that has '/' under the SOURCE column, and has a FSTYPE that doesn't correlate to a fsck.* command, will cause this bug.
