I thought that UFS file systems only fragmented when allocated blocks
in the last few percent of a disk while the allocation strategy of
VxFS (which I take to be the standard name of Veritas File System)
will fragment relatively quickly as it uses up the pools of large free
extents. This is why I thought there were no defrag tools for UFS file
systems (normally) and they're were for VxFS.
