We already do something like that in the Fedora spec file.  Actually
having multiple appliances is problematic because of the amount of
space and time consumed building them all, for little gain.

Note also there is a hard limit of 4 GB on the size of the appliance,
in practice I'd prefer not to go near that limit.

(b) seems like the right choice.

Given we have to use shell scripts, can we use 'set -e' in these shell
scripts?
