dhcpcd --slaac hwaddr

also works.
The problem I have is that most dhcpcd.conf options works on the commandline 
and most commandline options also work in dhcpcd.conf.
However, this is not 100% the case and have yet to work out how I can easily 
manage this in two man pages without over duplication.

Ideas are welcome :)

You could just preserve dhcpcd.secret as well to keep the same private 
addresses If you wanted to have that feature or not.
