Hello,
I've never got a feedback on this patch. Will it be integrated?
Thanks

The dmsquash-live module assumes that `overlay` is always a module.
Therefore, when `overlay` is built-in the kernel, this module will fail
to detect the presence of such a feature.
This patch adds a fallback mechanism to check also `/proc/filesystem`.
This is also what happens with the dracut NSF module when loading the
kernel module `rpc_pipefs`.
