Looks like they're all 3.8.0 based...

If you don't mind, I really have no idea how to do that. :)

Absolutely. If we end up using their services, we need to make them
aware and be in sync. :)

Also, we should incorporate that maintenance into the same package as
we did the last apt repo.

Just make sure Anton is in the loop, and we should be able to get it
going after the prototype is approved by the other users.

Guys, you are jumping on the gun.
There is no need to migrate to PPA or build.o.o.
llvm.org/apt was providing the mirror, not the build infra.
Changing the URL of the mirror is trivial, changing the build infra is a
complex work.

Clearly, I don't see any real issue in the current situation.

I think we all agreed that PPA was a bad idea from start, so don't
worry about it.

It's more than just an apt mirror...

Right now, only Debian based distros can use that apt repo, so if we
want to do the same for RPM based ones, we'll have to double the
infrastructure. Furthermore, I can see an argument to keep
distro-based storage in a distro-based infrastructure, not in LLVM, as
we probably should be distro-agnostic.

Dan was saying that the OpenSuse build can host files for all distros,
and maybe even build them, so I don't see any problem in *trying*
that. If anything, we'll end up with another distro being served in
the same way, and we could get Debian and Ubuntu builds to pull files
from there. Even if we go back serving the files from LLVM servers,
the Suse build can continue from the new location. I don't see any
harm in that... As you said, changing the mirror is trivial...

I'm happy with any solution that can be maintained for more than a
week without crashing other crucial LLVM infrastructure.

Sorry to jump the gun. I brought up OBS because someone mentioned PPAs
and I think PPAs in their current form are terrible.

Right now finding new hosting for the mirror seems like the most
important thing. Maybe the LLVM foundation should weigh in here?
Presumably there are funds set aside for something like this? Having
packages for different LLVM versions is incredibly useful and I think
help should be made available to you for hosting should you need it.
