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.

I think so, but there can probably be some vendor-specific differences, like storing the image in a place that doesn't get overwritten. For example, thinkpads provide a way to supply your own image, and when installing updates after that you're asked if you want to keep it. But yeah, the update should neuter it anyways
