Hi folks, just aquestion.
I am booting a lie system from USB-stick. In this live system I am creating an ISO-file, which I then want to dd onto another USB-stick. As I am doing this with a script, I want to make sure, that the correct USB- stick is used. Thus I can do by using the UUID of the target stick like dd if=/path/to/myfile.iso of=UUID="123456-abcd-............" This is working. Now my question: Whenever I dd to the target stick, does the UUID change? I know, the UUID of the partitions are changing, but what is with the device itself? Or is there a better way? Maybe by using a label? I read also about blkid, but does this change, too when dd to the device? At all, is my idea possible at all or are ALL UUIDs changing, whenever I do a dd? If yes, then how can this be prohibited, if any. Thanks for any help. Best Hans
