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 <i>precisely</i> what is on your system. No bloat. No extra dependencies. Apps compiled with support for "superfluous" features disabled, etc.<p>I owe my love of chroot to Gentoo.<p>The guide[1] is incredibly straightforward and easy to follow.<p>1: <a href="https://wiki.gentoo.org/wiki/Handbook:AMD64" rel="nofollow noreferrer">https://wiki.gentoo.org/wiki/Handbook:AMD64</a>
