As I just noted in the bug, this then introduces new sets of problems
instead
1) Running a livecd build breaks mounting usb sticks or other things
that you plug in
2) Running livecd-creator under some other command means that we lose
some of the care that we have around keyboard interrupting and having
that sanely clean up

So I really don't think that's the right "solution" to the problem as
instead it's just papering over the fact that devkit-disks thinks it
owns the world :/
