Yeah, I could have used deboostrap directly, but starting from the
lilydev ISO I didn't have to figure out what packages to install.
It was just a proof of concept after all.

And about the choice between guile 1.8 or 2.0.12/13, it should be
possible to have both guile-1.8 and guile-2.0 packages installed in the
same image and then let lilypond choose which one to pick up at
configure-time, shoudln't it?

Developers interested in comparing results would have two development
directories, one configured for guile-1.8 and one for guile-2.0.
