Why I did not stopped using NixOS and went back to Arch Linux

Knicks means police in the state/city of NY.

NixOS breaks. All. the. time.

Not for me.

Error messages are cryptic

Programming is like that. Learn how to use the repl.

Huge update sizes

No argument there.

Compilation takes forever (and binary caches are unreliable)

Wait a week.

Poor documentation

Read the source.

aconfmgr

I was looking for the on for Debian.

system-manager

You guys break my system alot. It's annoying. Stop.
