Difficult when there's no local reproducer and the compose logs lack
sufficient granularity: no kernel messages, and no user space messages
for the failing e2fsck.

Every compose has umount failures of one sort or another which itself
is not OK, it's just that usually there's no consequence. I don't know
enough about how composes work, but if the e2fsck runs in an
environment distinct from the install environment (like a VM) then
e2fsck doesn't know that the file system is still mounted in the VM;
nor that qemu cache unsafe means guest commits aren't guaranteed to be
committed on the host. So it could be either a delayed or failed
mount, or delayed host side commits from qemu's disk cache. Or
something else entirely.

Like I mention in the bug, throw spaghetti at a wall and change the
cache setting from unsafe to none and see if that fixes it. Locally I
use cache=unsafe all the time but it does result in non-determinstic
commit delays on the host, if something bad happens on the host this
guarantees data loss, and while the host isn't dying in this bug,
e2fsck might just be running too soon on the host to use this cache
option.
