Features:
-* add test targets to Makefile that runs all our tools with "--help"
- and checks if the output is identical to the output when passed
- through "fold -w 79".
-
* nspawn: emulate /dev/kmsg using CUSE and turn off the syslog syscall
with seccomp. That should provide us with a useful log buffer that
systemd can log to during early boot, and disconnect container logs
