I have tested the new packages for TW [1] and ALP [2]. In TW everything works
as expected (using Btrfs file system). In ALP (also Btrfs but read-only), the
criu simple-loop test works, but podman-checkpoint still complains:

$ podman container checkpoint distracted_babbage
ERRO[0000] container still running                      
ERRO[0000] criu failed: type NOTIFY errno 0

I have also tried this workaround [2] without success. Any further idea?
Thanks!
