Installing to a GPT partition

[Gerald Henriksen]

So a hard drive upgrade means there is no longer an old style drive,
which it appears installing Dragonfly in the GPT/EFI world is
currently an adventure.

The relevant partitions (using Linux descriptions) that I would like
to use are:

/dev/sda8 - EFI
/dev/sda9 - main Dragonfly
/dev/sdc5 - a 10GB partition for swap

Any suggestions/links on how to install Dragonfly in such a scenario?
