dynamic partitioning

Does anyone know how to create dynamic on-the-fly partitioning? (on SuSE Linux Professional 9.1) I have a heterogenous machine park with disk layout ranging from 1 to 4 disks and various requirements, i.e. raid on some, LVM on some, raid and LVM on some. I would like to create the partitioning scheme as part of the (lovely) automated installation process using autoyast. However, I've played around with the rules mechanism and as far as I can see, there's gonna be a lot of extra coding to cover every possible scenario as opposed to creating the partitioning on-the-fly. Also, does anyone have the XML XInclude feature working on SuSE Pro 9.1? I've tried and I just can't get it to work for me. Any hints? R -- stava@jonitec.se
