I've just implemented DUID-UUID for dhcpcd.
Patch here:
https://roy.marples.name/git/dhcpcd.git/commit/?id=71981cab0e41ea2833489bc51307611727276aff

Tested on NetBSD, OpenBSD, FreeBSD and Linux.
Unsure how to get system-uuid for Solaris or QNX at this time, which are 
the only other platforms dhcpcd works on (but isn't as well supported).
