NFS locking, and delay, and clock skew issues on the NFS 
servers vs. the build unit, make building in an NFS mount a 
painful experience.  Adding chroot just makes what needs to be 
a robust process more fragile

There is little percentage to nfs based build finesystems, 
unless it is one's only choice ... and with the way ram prices 
have moved in the last few years, tmpfs provides a clearly 
better choice
