I've been "aware" of systemd for a long time (and the holy wars around it) but to date have always used sysV init on embedded devices so this is first project with systemd so I have a bit of a learning curve. I wish I had it on other projects though as it is better at solving race conditions that happen ... like when you need to boot and mount and run from a USB NAND flash. Can't fsck or mount until it enumerates and that isn't always deterministic and udev rules and triggers were a moving target.
