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.

The I/O size is a reason why it's better to use cp than dd to copy an ISO to a USB stick. cp automatically selects an I/O size which should yield good performance, while dd's default is extremely small and it's necessary to specify a sane value manually (e.g. bs=1M).

With "everything" being a file on Linux, dd isn't really special for simply cloning a disk. The habit of using dd is still quite strong for me.

Interesting. Is this serious advice and if so, what's the new canonical command to burn an ISO?

Recently, I learned that booting from a dd'd image is actually a major hack. I don't get it together on my own, but has something to do with no actual boot entry and partition table being created. Because of this, it's better to use an actual media creation tool such as Rufus or balena etcher.
