[cisco-bba] 'mtu' versus 'ip mtu'

I 'upgraded' from 12.4(19b) to 12.2(SB11)31 this morning and rancid is
showing me that IOS automatically added 'ip mtu 1492' to my interface.  

I already had the following in there:
   mtu 1492
   ip tcp adjust-mss 1452
   ppp mtu adaptive

Do I need to set my ip mtu to some other value?
