The idea is to set the clock as early as possible, to ensure coordination
among log messages, etc. After udev by definition isn't as early as

That being said, we *could*:
- move clock setting later
- set the clock from a udev rule

Ideally, we could use the kernel support for automatically setting the
clock when the rtc driver is initialized, but that would require everyone
to have their clocks set in UTC, or have the kernel reading a userspace
config file.
