Hello!

I've a lot of new log entries after update top 2.4.0

dhcpleases 		kqueue error: unkown
dhcpleases 		Could not deliver signal HUP to process because its pidfile (/var/run/unbound.pid) does not exist, No such process.
dhcpleases 		/etc/hosts changed size from original!
dhcpleases 		/etc/hosts changed size from original!
root 			/etc/rc.d/hostid: WARNING: hostid: unable to figure out a UUID from DMI data, generating a new one 

How can I solve the problems?

Many thanks!
