So it's usually possible to set them to an arbitrary value, for e.g. a previously used value. Altough it doesn't necessarily mean that it is easy to do. For e.g. for both xfs & ext? filesystems you can change the UUID of the filesystem by using the appropriate cli-tool (xfs_admin/tune2fs). So it's easy to change the UUIDs for said filesystems. Or in other words: Everything in this directory can be manipulated to be how you want them to be: ls -l /dev/disk/by-uuid/ Whereas most things in this directory are derived from things that change when you switch devices: ls -l /dev/disk/by-id/ -- Matthias _______________________________________________ dm-crypt mailing list dm-crypt@xxxxxxxx http://www.saout.de/mailman/listinfo/dm-crypt
