RE: [Ltib] "Variant" platform builds

[seh]

Hi Bruce,

If you intend to run only in batch mode, you can skip the
--selectype/preconfigs.lkc and just save off the configs you want (to your
config/platform/_target_

You can the run them in batch mode with (from memory):

./ltib --batch --preconfig config/platform/_target_/config_file_name

If you switch configurations, ltib will detect this and do the appropriate
cleanup off the rootfs area before it continues.

Note that LTIB caches the rpms it builds along with other settings and so
if you swap back again, it won't need to rebuild the packages again (just
re-install).

Regards, Stuart
