Hello Sebastian,

I believe this has been discussed before although I can't find the
thread. I have concerns about the maintenance of snapshots. How many
target toolchains will we do this for, what frequency will snapshots
be taken, and how long will we preserve them?

Is there a different low-cost technical solution that can be used
instead of a snapshot? For example, we can check-out a specific commit
from a repository: wouldn't it work well enough to identify such
commits and update them periodically instead of taking a full snapshot
of the tool sources? I believe this is how we have dealt with qemu in
the RSB, by picking one commit and sticking with it for awhile.
