DESCRIPTION

14       The  dcfs  filesystem  is a layered filesystem that you use to compress
15       data when writing to a file and  decompress  upon  read.   The  primary
16       function  of  the  dcfs filesystem is to compress individual files when
17       constructing a boot archive and when reading or booting  from  the  ar‐
18       chive.
