For some reason I cannot reproduce this issue locally. I have tried both
on amdahl as well as a local arm64 system via sbuild. Here the logs of
the latter attempt:
https://people.debian.org/~ema/user-session-migration_arm64.build

The sbuild environment should match pretty closly what we have on the
buildds: sbuild 0.89.3+deb13u4 on trixie using the unshare backend.

Perhaps someone more familiar with the package can suggest how to try
and reproduce?
