I think that there is a bug lurking in the sense of trying to reuse
bitmaps when covering a pack that doesn't have reachability closure in
this particular scenario.
But there are no "blessed" use-cases for doing this. So I think that we
should indeed fix this, but I am not immediately concerned here.
OK.
No; we can either reuse a complete bitmap or not. So it's fine to OR
all of the (permuted) bits into ent->bitmap, but it's not OK to fill in
just part of them.
Sounds sane.
