OpenEmbedded "poky" with some sysmocom specific modifications. Mostly used only up to sysmocom release 201310, but the "pyro" branch is still used for 201705
For the IDU we currently want to have persistent log files. We
need to fork the volatiles script (installed as 00_core) and it
is already different between dora and current master of poky.
We are missing an sob-idu-qa check that verifies that /var/log
is not a symlink and that /etc/systemd/system/journald.conf is
set to persistent too.
