Small issue... https://wiki.archlinux.org/index.php/Tcplay

Creating the container: "# losetup /dev/loop0 foo.tc"

It may not be obvious to a new user, but "loop0" is already in use after "$ losetup -f".

"losetup /dev/loop0 foo.tc" could be changed to "losetup /dev/loop1 foo.tc" instead.

Thank You!
