[elbe-devel] Custom Kernel with elbe pbuilder

[Steih, Martin]

Hi Manuel,

thanks for this hint. That sounds like a great workaround. There is just a whired error message when I do something like

$elbe control create_project > Test.prj
$PROJECT=$(cat Test.prj)
$elbe control set_xml $PROJECT Test.xml
$elbe prjrepo upload_pkg $PROJECT /home/lr/Linux/linux-imagexxxxx.deb

it responds with an error message complaining there would not be such file or directory. In addition the project remains busy. 
Any suggestions about that?

If you use the 'elbe control' commands (create, set_xml, build) instead of elbe initvm submit, you can use 'elbe prj_repo upload_pkg' after a project was created to add packages to an elbe initvm internal repository that is automatically included while building the image. But also in this case you need to add the package to the pkg-list of your XML. It just helps in a way, that you don't need to build your own repository.

BTW. this repo also includes all packages built by pbuilder and is automaticly used by pbuilder to retrieve Build-depends from.

Also patches against the docs/* repository are very welcome for all kind of tutorials.
