I know about Clonezilla and copy pasting partitions with gparted, but can I just use dd to copy a partition with batocera to a USB stick and will it then boot from the stick? Do I have to set the boot flag or take any other steps?
Thank you for any tips.
Because it is in use. You technically can hot swap a file system by switching run levels and temporarily switching to a tmpfs but I’ve never succeeded.
