maybe, yes.

the quoted bit from me is still very true.

that and I'm not sure how much your desired way of testing u-boot
is generally useful.

again: I'd like to rebuild against the actual archive (first, before I'd
working on improve our 'theoretical testlab' again). That said, as
always, patches welcome and existing patches I'll likely happily merge.

I'm sorry to sound so "negative", I'd just like to focus on the actual
rebuilder thing. Which *is* shaping up, just slower than I'd like.
