No, not if the intention is to build a FreeBSD distribution; however, the
point of shimmer is to build something a little more custom. What I posted
begins to break the various parts of the system down into packages, and only
installs what is required to boot and be minimally useful. mktree allow us
to package things into more complex groupings to build different custom
'distributions' from a single shimmer tree.
I didn't clame it was going to change the world, only that I would like to
see someone benefit from my work.
Did you actually look at what was there?
