Ah I see, should there be a pre-existing /LiveOS/home.img it should be
deleted and recreated when that option is used on the cmdline. Got it,
been away from the livecd stuff for awhile, used to be really active on
the livecd mailing list a few years ago.

Now with using --format there will be no chance of saving a
pre-existing /LiveOS/home.img for reuse anyway, so no need to delete
home.img before hand. Maybe drop that option?
