Hmm, I thought it had gone away.

Yes, as Ive come to find.

I knew that, but I was not doing it right in this case and it was the cron
job for save-entropy that was causing grief.

Knew it had something to do with that, just wasnt quite sure of the
details.

Aye, that I will try now that I know.

I do some stuff from ports, some from source, and now that I know for sure
what to do that will fix that.

As for the permission denied, that would show up in the dhcpd log every 11
minutes. :)

Dhcpd was starting fine and running, but operator would try to start it
again every 11 mins from cron. Its been running fine now since I got the
rc.conf issue worked out.

Thanks muchly for this.
