(CC-ing the existing ZoL Debian packaging team, although there is hardly
ever any response there..)

as an upstream contributor and with my downstream/derivative hat on I
have an alternative proposal:

I've been pondering cleaning up and pushing the existing Debian
packaging (or some variant thereof) upstream to replace the ugly "build
rpms and use alien + various hacks to get some sort of .deb output"
"build system" that is currently used.

it seems like upstream is just lacking the people and knowledge to do
this, but it would be welcome (see config/deb.am). would you be
interested in teaming up on this?

there are quite a lot of people running git master or the latest 0.7.x
release on some variant of Debian/Ubuntu that get tripped up on every
other release because of missing files and lack of integration into
Debian tooling, probably more than would be willing/able to track
experimental ;)

this would also have the big upside of being able to integrate the
upstream Debian packaging directly into zfs-buildbot infrastructure,
hopefully keeping most of the packaging-related issues we've seen in the
past from being part of any tagged releases in the future.

the only real downside I see is the fact the the debian/ folder would
need to be excluded when importing stable upstream releases into Debian
proper, in favor of cherry-picking the relevant packaging changes only
as separate commits afterwards (but this is easy with the existing GBP
workflow, and something that a lot of packages with upstream debian/
folders handle just fine).
