I’m planning to install Arch Linux for the first time. Any recommendations on setup, must-have applications, or best practices? Also, what’s something you wish you knew before switching to Arch?
Arch was the distro that got me to stop distro-hopping. It's stable, it has a rolling release, and it's mine (as in, customizable, manageable).
I guess, if there's anything I wish I'd known off the bat is that the Arch documentation is probably the best available. So much so, a LOT of it applies to Linux in general and not strictly to Arch.
If something breaks, READ the error messages, understand each component, and check the wiki, there's a very high chance the troubleshooting section has the exact issue laid out.
