I thought pump was only a client, not a daemon.   dhcpd is from the BIND 
folks, ISC -- which either says something good or bad for reliability 
depending on how far you took BIND 9 and tried to actually USE the new 
features early on, and how much hair you pulled out trying.  (GRIN... 
just kidding.)

I don't think you can migrate them, but you should probably turn the 
lease time down well in advance.  Of course, if the machines are sitting 
there with leases for 6 months and never get rebooted, they're just 
going to have to reboot them.

That's an interesting move.  Of course, I don't want to bash linux, but 
if the clients are all Windows, (here it comes... a rare kudo for MS 
from me...) the MS Active Directory/Windows network browser junk/DNS 
server seems to do fine if enough Active Directory/DNS servers are 
configured and running.  What caused them to want to move to Linux for 
DNS internally?  The other kudo for the Windows stuff is that dynamic 
DNS appears to actually work pretty well most of the time.

Far from a Windows fan, for handing internal DNS for desktop machines, 
it seems to do fine.  Probably wouldn't run it for public DNS stuff 
though, but you can slave a BIND machine from it for that... GRIN.
