For three examples - two trivial, one complex, of custom builds, see
http://wylie.me.uk/static/rock/ - target "alan" - just remove some
unwanted packages, "nogk" - as alan, but no Gnome or KDE, and "frog" -
a minimal web server.

Basically, you want a sed script in config.in that filters the
incoming package details, either deleting the lines entirely, or
replacing the "X" (enabled) at the beginning of the line with "O"
(disabled).

The details are read from the .desc files for each package and written
to config/xxx/packages. Note how the [P] line matches the start of the
line in .../packages. Thus packages can be disabled either in the
.desc file if the character after "[P] " is O, or by the sed script.

You can also set the configuration variables that you see as check boxes
when running the configure script by adding a line such as 
ROCKCFGSET_PKG_PERL5_USE_DB3='0'
to your config.in file - this will set the environment variable 
ROCKCFG_PKG_PERL5_USE_DB3 in config/xxx/config

You can add a custom linux kernel .config by copying it to kernel.conf
in your target/xxx directory
