There's a workaround, though: you first restore to a partition big enough and the you use parted to reduce it to lower limits.

Is there a way to copy an image of just the files from one drive to another? In the case where the 10GB indeed has mostly only files in its lower 5GB, it might be worthwhile to do something like: resize2fs /dev/foo 4G and then to `dd' the first 4GB only. But in all likelyhood cp -a, tar, or rsync will be more efficient. Stefan -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe. Trouble?
