I can think of at least one cluster where the opposite has been true and
PXE boot has been the default.  The problem with this is if the head
node PXE boots on the customers network and gets automatically
re-installed as a windows workstation everybody gets egg on their face.
Yes even "modern" BIOSes are bad but localboot first is a sensible
default.
