Do Write Memory and DHCP !!! Not always Best Bet

Lets go to IOS and experience an interesting case

R1(config)#ip dhcp pool Strange

Oh wait a min, I want to save my Config !!! Lets use write mem or do wr

R1(dhcp-config)#do wr
R1(dhcp-config)#end

Now My Config is save, let see show run output

Sh run
Output ommited....
!
ip dhcp pool Strange
domain-name wr------------> Ooops watch that.....where the domain name comes!!!!
!

My God this made me totally mad during an implementation, i were able to figure out this after sometime. So beware of shorcuts they are not always good (:
