you can put the /dev/disk/by-id/$disk_id directly into your disk_config. where $disk_id could be the WWN, serial number or other identifiers generated by kernel+udev on your hardware. I have a mechanism in place that aborts installations without this setup when more than 1 disk is visible, therefore: - I only have to provide explicit disk configs for storage servers - but all the boring HPC nodes and simple servers take the generic partitioning classes -- Mit freundlichen Grüßen Henning Glawe Dr. Henning Glawe Max-Planck-Institut für Struktur und Dynamik der Materie Geb. 99 (CFEL), Luruper Chaussee 149, 22761 Hamburg, Germany http://www.mpsd.mpg.de/, Email: henning.gl...@mpsd.mpg.de Building/Room: 99/O2.100, Phone: +49-40-8998-88392
