Hi,

Thanks for your patch.

I note it does conflict with some other patches currently in testing,
and once these conflicts solved, I get some bitbake-selftest errors:

ERROR: test_crate_fetches_from_local_sparse_registry (bb.tests.fetch.CrateTest.test_crate_fetches_from_local_sparse_registry)

https://autobuilder.yoctoproject.org/valkyrie/#/builders/23/builds/3960

Maybe the easiest solution is to wait a few days until said patches are
either merged or rejected, then send a refreshed version.

If you want to have a look at the current situation, here is the branch
that was used for above builds:

Thanks,
