Features:
+* there should be path_hash_ops and we should use it in tmpfiles' hashmap object to deal with identical but differently spelt paths
+
* rework pid watching logic, allow any number of units watch the same pid
* be stricter with fds we receive for the fdstore: close them asynchronously
"systemd-gdb" for attaching to the start-up of any system service in its
natural habitat.
+* replace all canonicalize_file_name() invocations by chase_symlinks(), in
+ particulr those where a rootdir is relevant.
+
* maybe introduce gpt auto discovery for /var/tmp?
* maybe add gpt-partition-based user management: each user gets his own
