* start using STATX_SUBVOL in btrfs_is_subvol(). Also, make use of it
generically, so that image discovery recognizes bcachefs subvols too.
+* "systemd-export tar" should reuse the libarchive export code from systemd-dissect
+ --archive.
+
+* "systemd-import tar" should be moved to libarchive
+
+* foreign uid:
+ - add support to export-fs, import-fs, import-tar, export-tar
+ - add tool for deleting foreign UID held container images
+ - systemd-dissect should learn mappings, too, when doing mtree and such
+
* format-table: introduce new cell type for strings with ansi sequences in
them. display them in regular output mode (via strip_tab_ansi()), but
suppress them in json mode.
