Looks quite good. I've read through your changes and they seem
sensible.

Yeah, we could probably just drop that xkb-data >= 1.4 version
dependency entirely; we're up to 2.5 now. Not sure if the xfonts-base
version dep is really that important either; the package changes very
little anyway.

I'm not seeing a versioned depends from plymouth here?

Maybe we should SRU this change since this causes trouble, and eliminate
the potential for an issue. It's checking for xkb-data 0.8 which is
ancient history now, so is really quite useless. RAOF, does such a
thing sound SRU-able to you?

Should this be "to add" or "to drop"?
In any case, this should be fine to include. Also maybe SRUable?

Doesn't matter. These look to be Debian's bug reporting scripts, but we
don't use them at all; we use apport and our xorg apport hook is a lot
more sophisticated than these.
So, you can rename or leave alone or even just delete them, whatever's
the least trouble to do.

Nice, I'll give this procedure a shot.

Looks good to me. Call it done, and any further tweaks can be handled
as ordinary tasks.
