What config error causes chrony to die? The config file is parsed
before daemon(), but they are not treated as fatal, just warnings.
Should chrony abort if there are any?
This does it:
rtconutc
rtcsync
Also, these logs from something which died on startup (I'm messing with my kernel clock delay calculation)

Well, that should generate a fatal error, since chrony cannot correct it,
because the kernel clock cannot be adjusted that much. Ie, chrony is useless
in that situation and should die.
That is not a config error. It is a "hardware" error-- the clock is
irredemably broken. (Fortunately it was just your kernel config that broke it
so you could recover, but chrony could not)
