Re: multistrap support

[Henning Schild <henning.schild@siemens.com>]

Hi,

in fact Isar does not really care too much about how exactly
setup_root_file_system does what it does. Just the interface has to be
stable at some point. So you take a list of repos and packages and off
you go ... to put it overly-simple.

rootfs = strap(repos, package-names)

That is why the switch from multistrap to debootstrap was relatively
simple. So you could even think about switching back or switching to
yet another <funny>-strap.

What i would like to understand is why you care about multistrap and
why you think the strap-tool has an implication on collaboration with
other projects? Where do you see the risk of not being able to share
efforts with other projects that use multistrap?
