This message deals with NO PROBLEM, nothing wrong, nor issue to solve.

It is just a discussion about something I don't get.
I'm using DHCP since more than a decade in very complex failover setups, 
I'm using numerous script-generated hundreds of page dhcpd.conf servers 
amongst hundreds of synced sites.
All this is working flawlessly.

Though, I've never understood in what cases it should be important to 
keep safely the dhcp lease files. I mean, for dynamic leases hosts, they 
just will have to issue new queries - this won't load the servers as all 
those hosts lease time has been randomly spread in date and time, so 
their queries won't burst all in the same time.
And for the fixed lease, there is neither a hurry to get a reply because 
if the dhcp infrastructure replies lately, the dhcp implementation 
allows late query retries in time.

So, I don't see anything horrible happening if I loose all my leases 
files and restart my servers...?
