I upgraded to a new harddisk by using dd to copy the partition. As the old disk is still in place, the computer seems to randomly boot one or another. To fix this I thought, changing the UUID/LABEL of the disk and adjusting /etc/fstab accordingly might help.

However I don't find a command with similar capabilities as tune2fs. Any suggestions?
