It seems the following qemu commit changed the needs for the backing
image rules:
(qemu) commit 244a5668106297378391b768e7288eb157616f64
Author: Fam Zheng <famz@xxxxxxxxxx>
file-posix: Add image locking to perm operations
Additional Note (but not part of the patch description):
I thought at first I'd be on the "old kernel but new glibc" case of [1] in qemu.
But as explained in the patch it turned out that instead my kernel was new enough and instead I ran into apparmor denials.
Even if that change would be accepted in qemu we would still need the apparmor fix I proposed here, but it is valid context that people might be interested in.
