* rework journal-send.c to use memfds for large blobs if they are available instead of unlinked files in /tmp. Also, if we detect that the kernel knows memfds, refuse anything but sealed memfds.
* maybe support a new very "soft" reboot mode, that simply kills all processes, disassembles everything, flushes /run and sysvipc, and then reexecs systemd again
