I added some debugging to /libexec/dhcpcd-run-hooks and things started 
working ... better.

I created an empty file called /var/log/debug and added "exec >> 
/var/log/debug 2>&1" to the top of /libexec/dhcpcd-run-hooks.

With this change the hostname is reliably set by the time I ssh in to 
the Raspberry Pi after a reboot, but the hostname is not set quickly 
enough for Postfix to notice it and the initial hostname prompt on the 
console still says "Amnesiac".

Every time I reboot the Raspberry Pi, I get one more line in 
/var/log/debug that says "usmsc0: Setting hostname: 
rpi3-1.must-have-coffee.gen.nz".

Cheers,
Lloyd
