febootstrap is intended for building supermin appliances, see:

Thanks Richard! Maybe a better question would be what are the use
cases for supermin appliances? What are they not suitable for?
What I'm after is something akin to a Solaris sparse Zone. i.e. most
of the files are the same are the parent OS except the website's data
files, a tiny amount of config and it needs to be jailed off from all
the other hosted sites.
It would seem that an on demand launched supermin with the web server
config, ip address and a document root would fit well? Apart from
these bits of data all the containers would be identical. In fact we
very much want everything else to be the same.
