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.

That is not a replacement for "arrow-key down during boot to select an older kernel".
I have a server with a RAID card and the kernel at some point introduced a bug with the driver that prevented that server from booting. So I select the older kernel at boot, get the system up and running, mark that kernel as the default until the bug is fixed.
I know how the system works very well thankyouverymuch. But that's an insane option when having multiple older kernels is so easy to do and common.
As said: installing the LTS kernel also works, I think.
And you wouldn't use Arch for servers, you want something stable (as in “rarely changing”) there.
