func MountsToLayer ¶

func MountsToLayer(mounts []mount.Mount) (string, error)

MountsToLayer returns the snapshot layer directory in order to generate EROFS-formatted blobs;

If mount[0].Type is `bind` or `erofs`, it just tries the source dir; Or if mount[0].Type is `overlayfs`, it tries the parent of the upperdir;

The candidate will be checked with ".erofslayer" to make sure this active snapshot is really generated by the EROFS snapshotter instead of others.
