I had long discussions with Michael Tautsching about these topics about 1-1.5 years ago. Check the list archives. Basically, with the various combinations of re-sizing and partial re-creation of partitions, it was much easier to program setup-storage to re-create all partitions at all times. There is one exception, though: if you specify "preserve_always:all" this is taken literally to mean that the existing partion table should not be touched at all. My solution has been to manually set up the dual-boot machines' partitions with the gparted (booted from a CD) and then use the above-mentioned option to install Debian via FAI. This works if you have just a handful of machines to set up (like we do). For obvious reasons it does not scale well :-) . Caution: the development by M. Tautschnig was done in the "experimental" branch of setup-storage, and I am using this version. I believe that the "preserve_always:all" new semantics made it into the trunk, but I am not 100% sure. So you should check yourself, and possibly use the "experimental" version (fai wiki has a page explaining where to get it). Different versions of setup-storage and the rest of fai can be combined freely, so you need not replace the rest with the experimental version unless needed for other reasons. Unfortunately Michael has disappeared from the list some time ago. Does anyone know what has come of him? He was very helpful in developing setup-storage. Toomas
