I find myself the oblique topic of discussion on the Arch forums recently. Although I guess the real issue is a comparison between Arch and Crux, so I’ll stop flattering myself.
I don’t have anything to add to the debate that I didn’t tack on to the end of the thread, so if you’re debating trying one or the other, you might skim through the pros and cons. If you’re a Crux user you’ll no doubt appreciate the immense load of precompiled software available to you. And of course if you’re an Arch user you might find the similar structure and sparse setup to your liking.
In the end, it’s all the same flavor, friends. Linux is Linux, I always say. Use what you like, and you’ll be happy.
