4.3BSD added the wonderful feature that a directory with unused disk blocks at the end is truncated when a file is created, since create has to search the entire directory anyways it can also detect empty directory entries. On our Suns running 4.0.1 this does not seem to be happening, I have noticed emtpy directories that are over 100K in size, most notable /usr/spool/news/.rnews and /usr/spool/mqueue. I know that the 3.X NFSSRC is based on 4.2BSD ufs code and does not have it but I thought that 4.0 would pick up the 4.3bsd features. Anyone have any insight on if this was deliberate or just an oversight? David Robinson elroy!david@csvax.caltech.edu ARPA david@elroy.jpl.nasa.gov ARPA {cit-vax,ames}!elroy!david UUCP
