This is really odd. I cannot reproduce, and looking at the code I
cannot figure out how this could ever happen. I pushed a bit of extra
logging just now, but even so I really don't see it.

Any chance you can reproduce this locally and either let me know how,
or go step through it with gdb and see where the EPERM originates?

This is expected if run as non-root (we need some caps to run the dhcp
server), it is just a SKIP and not a FAIL, so that is fine.
