Hi Carsten,

I also talked to elbrus on MiniDebCamp in Brussels. He explained to me
some details about the migration process I didn't understand before.
This will help us to identify the cause of some blockers by looking up
the information in the britney log.

As far as I could trace it, this leads to the packages listed in
https://people.debian.org/~infinity0/rust/debian-testing.txt

Most of the times when I take a detailed look on why it doesn't migrate,
it leads to one of the few packages that currently are in NEW. I don't
have the time right now to include it in this mail, but if desired I
will assemble the list of required packages that are currently in NEW as
soon as I find the time (hopefully tomorrow). A special case is the
rust-compiler-builtins source package that has been rejected by NEW
before due to unclear license information.

There is another issue that might need to be resolved that affects
mips[64]el, which is present in rustc (#950583) or possibly one of its
deps) surfacing in one of our crate packages (#950337). Due to that we
might be keeping versions in mips[64]el testing that block upgrades.
This can be seen in the rust transition tracker
https://release.debian.org/transitions/html/rust.html where a whole lot
of packages can not be built in mips[64]el due to this directly or
transitively depending on the affected package.

That is good to hear and would facilitate the procedure of updating
existing crates significantly.
