Can You Use Linux Without the Terminal? (How to Geek article)
(www.howtogeek.com)
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 tools like YaST help to save time, instead of editing the bootloader in config files, you can simply enter, search for "Boot Loader" and edit there, be following a tutorial or official documentation. I sometimes prefer to use YaST just so I don't do things wrong. it's like the old Control Panel in Windows.
YaST is great.
