How to read this table

The table has five major columns.

  1. src.conf

    The name of the option being tested

    All options are tested both in their WITH_FOO and WITHOUT_FOO variants but if the option has no effect (ie: is the default) it will not appear in the table

  2. MK_FOO

    Internal build flags affected by this option

  3. Buildworld

    What happens when the option is given to buildworld but not installworld

    Ie:
	make buildworld WITH_FOO=yes
	make installworld

  4. Installworld

    What happens when the option is given to installworld but not buildworld

    Ie:
	make buildworld 
	make installworld WITH_FOO=yes

  5. World

    What happens when the option is given to both buildworld and installworld

    Ie:
	make buildworld WITH_FOO=yes
	make installworld WITH_FOO=yes

Inside each of the last three major columns there are five subcolumns

  1. A

    Number of added files/directories (relative to the option not be given

    If non-zero, the number links to a list of the added files/directories

  2. D

    Number of deleted files/directories (relative to the option not be given

    If non-zero, the number links to a list of the files not installed files/directories

  3. C

    Number of changed files/directories (relative to the option not be given

    If non-zero, the number links to a list of the files/directories which are differnet (two lines each)

  4. KB

    Size of installed operating system in kilobytes

  5. Delta

    Size change in kilobytes relative to the option not be given
