Like tweaking the /etc/fstab accordingly, which genimage does not do on
its own?

So this "genimage fs" would not be so complex, but not so obvious either,
to write, as we'd need to have some additional script that does the fstab
tweaking... Probably that info would have to be scrapped out of the
genimage.cfg file.
