Bored? How about trying a Linux speedrun? (2020)
I recommend anyone wanting to learn Linux to deploy a Gentoo machine. It gives you a crash course in all of the various components, allows you to hand roll/customize your kernel, and provides incredible granularity in tuning precisely what is on your system. No bloat. No extra dependencies. Apps compiled with support for "superfluous" features disabled, etc.I owe my love of chroot to Gentoo.The guide[1] is incredibly straightforward and easy to follow.1: https://wiki.gentoo.org/wiki/Handbook:AMD64
