There are three distinct sets of files associated with a port: 1) The port-and-FreeBSD-specific config files which are stored under /usr/ports/<category>/<portname>. These files comprise a Makefile, various package files in pkg and various optional patches and scripts. 2) The original distribution file. This may be located anywhere on the internet (the location and name is in the port Makefile) and will be stored in /usr/ports/distfiles after download. These can be in any format, but .tar.gz is probably the most common. 3) Pre-built ports available as packaged from ftp.freebsd.org. I think these are all .tar.gz, but some might be bzip2 format. The discussions have all centered on 1) above. This is the area where there is the greatest wastage of resources (inodes and unused partial blocks). > - No need to CVS commit ar files.

The problem is that the diffs between 2 uuencoded .tar.gz files (which is how CVS would treat them) tend to contain the entire contents of both files. >> Disadvantages: - CVS files will bloat. - relatively difficult to examine the innards of the files for each port.
