* testing tool for socket activation: some binary that listens on a socket and passes it on using the usual socket activation protocol to some server.
-* journald: add symlinks and device names to kernel messages
-
* maybe make systemd-detect-virt suid? or use fscaps?
* consider using __secure_getenv() instead of getenv() in libs
-* journald: automatic rekeying with no log messages doesn't appear to work
-
* man: document in ExecStart= explicitly that we don't take shell command lines, only executable names with arguments
* shutdown: don't read-only mount anything when running in container

* switch-root: sockets need relabelling
-* segfault in journalctl during /var migration

* systemd-analyze post-boot is broken for initrd
* man: clarify that time-sync.target is not only sysv compat but also useful otherwise. Same for similar targets
-* journalctl should complain if run with uid != 0 and no persistent logs exist
-
* .device aliases need to be implemented with the "following" logic, probably.
* refuse taking lower-case variable names in sd_journal_send() and friends.
