A beginner to what, to pacman, to arch, to rolling distro, to linux, to unix, to a PC, to using man-made tools ...
I made an installation to an old pc once, I though it would last a while, and since the users could barely understand what an on/off button does, they just wanted google and facebook, so it was a wm with two browsers, daughter already knew what chrome was, and in the login shell I wrote a script that each new day it booted it attempted pacman -Suy --noconfirm then once a week the cache was emptied and the logs trimmed.
That was before covid, a couple months ago I met her, she said it has been working fine every since.
So there is your dinner
PS Actually it wasn't arch it was artix with runit but that is about the same
quick, quick, explain in one sentence whether the newb should go with musl of gliMBc ... hurry ... the screen is about to turn black and the installer will be gone
