Is there a way to assess which packages on my linux distribution aren’t open source? I’m planning on having a secondary machine which is exclusively open source, but not sure how I would go about ensuring that is the case.

Great! This is the kind of answer I’ve been looking for. Thank you.

Agreed - the message I was trying to convey is that I use a very secure password, which sacrifices convenience for security - is this necessary though? I have no concerns related to memorising or particular difficulties typing it out as it follows a passphrase structure for the most part.

Arch wiki is superb, couldn’t have installed or configured Arch without it.

In a way this post is just long-form “I use Arch, btw” 🤯
