> Yup. NixOS was the first OS I used where upgrades weren't a big deal. No time waiting for upgrades. No time worrying about them.

One of my favorite lesser benefits of using NixOS is that running a big system upgrade doesn't even stop you from installing software while it's running. Realize you need a new program while your system upgrade is running? No problem! Add it to your NixOS configuration for posterity if you like, then run it in a Nix shell or install it to your user profile. No need to interrupt the upgrade or wait until it's over.
