ubuntu_aufs_smoke_test failed on Focal OEM 5.6

[Po-Hsu Lin]

Issue found on OEM 5.6 (5.6.0-1010.10-oem)

Test failed with:
    mount: /tmp/aufs/aufs-root: unknown filesystem type 'aufs'.

Need to check if 5.6 supports aufs.

[Po-Hsu Lin (cypressyew)]

CONFIG_AUFS_FS was removed in commit 6940426c "UBUNTU: [Config] updateconfigs after rebase to 5.5-rc1" in the OEM 5.6 Focal tree.

Next is to figure out why it's removed there.
We still have aufs code in the tree (but not in Linus's tree upstream, so maybe it's intended.)

[Po-Hsu Lin (cypressyew)]

It looks like the AUFS config support was added in commit f9ec9ce6 "UBUNTU: [Config] enable aufs"

So this might be just a decision making, do we need to re-enable this support in F-OEM-5.6

[Po-Hsu Lin (cypressyew)]

We do have this config re-enable in the F-OEM-5.6, it should be in debian.oem, not where debian.master that I checked.

Timo:
for some reason the module is not included
though it's on the inclusion list
well, it's not even built

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-focal' to 'verification-done-focal'. If the problem still exists, change the tag 'verification-needed-focal' to 'verification-failed-focal'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!
