The particulars are that I've rebuilt a Fedora LiveOS filesystem image from
a currently running instance (incorporating the filesystem changes in the
device-mapper overlay into a new base filesystem image file).

I'd like to halt the active rootfs, switch to its mirror, copy over the
halted filesystem image file with the refreshed version, and then switch
back.
