use name_to_handle_at and open_by_handle_at to persist rootless namespaces without needing a pause process. The namespace file handles are stored in a file and can be used to rejoin the namespaces, as long as the namespaces still exist. Fall back to the pause process approach only when the kernel doesn't support nsfs handles (EOPNOTSUPP). The feature is currently only enabled when the PODMAN_NO_PAUSE_PROCESS environment variable is set. These changes in the kernel are required (landed in Linux 6.18): https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=3ab378cfa793 Signed-off-by: Giuseppe Scrivano <gscrivan@redhat.com>
