thanks

Hello Paul,

Thanks for this report. I am forward it to the upstream author.

Lars, this bug is related to filesystem options, in a very similar fashion
to #1031364 which was fixed in late 2022. Could you also please take a look
and give us your opinion?

Thanks!

Package: vmdb2
Version: 0.40-2
Severity: normal

Hi,

I think the situation is similar to what happened during the
bookworm release in bug #1031364, but now with the option
orphan_file. Today I noticed that on ci.d.n the tests that use qemu
fail when running tests on oldstable (buster) because the image
(which is built with autopkgtest-build-qemu which uses vmdb2 under
the hood) doesn't boot. When I run the test manually with the
--show-boot option enabled in autopkgtest's qemu backend, the test
ends like below. The test hangs for 1 minute after """/dev/vda1 has >unsupported feature(s): FEATURE_C12"""

This seems to have started to happen after we upgraded the host from >bookworm to trixie.

I suspect that the code here needs to be expanded: https://sources.debian.org/src/vmdb2/0.40-2/vmdb/plugins/mkfs_plugin.py/#L63

I'll also note that it seems that code should depend on the target
suite and should only be conditionally applied.

Paul
