New Revision: 264027
URL: http://svnweb.freebsd.org/changeset/base/264027

Log:
  Add a new release build variable, WITH_COMPRESSED_IMAGES.
  
  When set to a non-empty value, the installation medium is
  compressed with gzip(1) as part of the 'install' target in
  the release/ directory.
  
  With gzip(1) compression, downloadable image are reduced in
  size quite significantly.  Build test against head@263927
  shows the following:
  
   bootonly.iso:		64% smaller
   disc1.iso:		44% smaller
   memstick.img:		47% smaller
   mini-memstick.img:	65% smaller
   dvd1.iso:		untested
  
  This option is off by default, I would eventually like to
  turn it on by default, and remove the '-k' flag to gzip(1)
  so only compressed images are published on FTP.
