Hi all,
I've installed 10.99.9 from about a day ago onto an old Raspberry Pi and 
I just can't get it to correctly set its hostname from DHCP. (I have 
removed the hostname=rpi from /etc/rc.conf).

What I have discovered so far is that if I manually run "dhcpcd -d" then 
no hostname gets set. If I run "dhcpcd -d -B" then the hostname does get 
set. This doesn't make sense.

Here are the logs from the failed run (console and /var/log/messages). 
Dhcpcd doesn't seem to be running the hooks for the "CARRIER", which is 
something that does happen with dhcpcd -d -B". Interestingly, the 
message "executing: /libexec/dhcpcd-run-hooks ..." is not logged to 
syslog by either invocation of dhcpcd.

Any advice would be welcome.

Cheers,
Lloyd
