[Nix-dev] Clear all

[Mathijs Kwik]

See http://nixos.org/wiki/Howto_keep_multiple_packages_up_to_date_at_once
That way, you install (and upgrade) only 1 package through nix-env and
keep everything in there.

To clean up:
nix-env -q | xargs nix-env -e

Then install your "my-env" package.

Regarding your second question:
Depends on who uses it.
If your system has multiple users, you can keep stuff like firefox in
systemPackages, so it's available to everyone. Of course if every user
installs it for himself, it will be shared anyway, so this is not a
space-saving, but just a convenience.

You can go a step further and define multiple sub-profiles.
For example 1 you typically use during c development.
And another for haskell development, and yet another for an
experimental python3 environment.
Then you can jump between those environments on a per-terminal basis
(no interferance, do many different things at once). Like this, you
keep the default packageset (and thus "commands" available in your
shell path) to a minimum. Look for "myEnvFun" in nixpkgs if you want
to try this.
