This is for SLES 11 SP1 SDK DVD support (Patch 1)
====================================================================
Patch Reason: Design changed, To make the code easier to maintain
we decided not to automate select autoyast config template file
(compute.sdk.sles11.tmpl/compute.sles11),
Patch detail: If the user want to do a SDK DVD included full install,
he/she should prepare a customized template originated from
compute.sdk.sles11.tmpl, and copy it under /install/custom
====================================================================
====================================================================
Target Dist: SLES 11 SP1, for both full install and statelite install
Aim: To enable users to install packages from SDK DVD during installation
user impact: If the user add packages in .pkglist files, he/she should first do 'copycds' using SDK DVD iso.
For full install, the user should prepare a .tmpl file for autoyast
By-effect: N/A
Limitations: 2nd installation DVD and 2nd SDK DVD not supported, both carries source packages.
It seems they are not recognized by autoyast, and it's of no use to install sources pkgs on CNs.
