From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

It might work, but probably not without a little tweaking.
A lot of things will reference drive identifiers or drive path to know where to mount them. These things don't get copied by dd.
huh?
Isn't it the other way around?
I once cloned an nvme with dd and had to physically remove one of the two, because they had the same id and the bios couldn't differentiate between them and would randomly boot into either the first or the second one, inconsistently.
And removing either one would boot into an identical system with everything mounted and working. Which caused some confusion until I realized that the id was copied over.
So unless you didn't use the id in fstab, you should be fine. Sure the device path may differ, but that can happen anyway to usually devices should be referenced by id.
There are different schemes that different distros use. Some user partition id, some use fire system id, and some use device serial number and partition index.
Thanks, so just update the UUID in fstab for the stick? Or is there more?
Probably all you need to do is check to make sure things look right, and actually test it.
I can't think of anything else that would be common that you'd want to check. If you're running weird virtualization setups on your laptop you might have to do more. :P
dd'ing /dev/sdx will copy all IDs
dd'ing /dev/sdx1 will keep UUID but PARTUUID will remain the same on the destination
