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.

Can I just use dd to clone my laptop to a bootable USB stick? (suppo.fi)

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.

I wouldn't recommend this as cp might not persist file ownership and permissions or maintain hard/soft links properly.

I guess, she meant copying not files but block devices, like cp /dev/sda1 /dev/sdb1. With GNU cp this indeed works similar to dd.

That's cool, I didn't know you could use cp on partitions.

My bad, forgot that.
