[PXE installer]how do I fire a custom script or add a package?

[sokoow]

Hi All,

I\m trying to do automated installs of mint using PXE and I'm struggling with installing packages or firing post install scripts using ubiquity. I tried to do this the way it's normally done in Ubuntu, but it doesn't really work. Is there any mint-specific way to do this ?

If this is a wrong place to ask this question, could you point me to the proper channel for this pls ? Thnks
