I'm setting up a pair of machines with almost identical OS config, and

It looks like I can use DD to copy an entire drive, but it's a 500G drive and
that's going to take a really long time (especially since it's brand new with
no data besides base OS).
My question: Is there a better way to duplicate a drive including boot info?
The way I've done that in the past is to backup the source system with
dump for /, /var, and /usr.
Then do a minimal install on the clone, setting up the appropriate
partition sizes. That is quicker for me than trying to remember fdisk
and bsdlabel options. It also avoids the embarrassing situation of
getting source and destination disks mixed up when they're both on the
same machine.
On the clone, restore from the original dump files over the new system
with "restore -ruf dumpfile".
