[Nix-dev] some basic questions from a new NixOS user

[Marc Weber]

You're welcome.

> 1a. I've added a new user account with "useradd," per the manual, and

3 ways: 
1) /var/run/current-system/sw/bin/ like installation by configuration.nix
2) system wide root installation ? (not sure about it)
3) user installation.

All can be rolled back. nix-env --list-generations etc (see man or do
--help).

Looks fine to me.

Read /etc/bashrc carefully. The answer should be there what is added to
PATH by default. Because I use my own patched version I'm not very sure
about it. That's point 2) above.
