John Ericson f7c896cfd8 Dedup some markdown -> C++ big literal stuff in build system 
This pattern rule was unwisely hidden in `src/libstore/local.mk`. Now it
is properly in `mk/` and we reuse it for the profile docs too.

Description

nix profile allows you to create and manage Nix profiles. A Nix profile is a set of packages that can be installed and upgraded independently from each other. Nix profiles are versioned, allowing them to be rolled back easily.

Profile compatibility

Warning

Once you have used nix profile you can no longer use nix-env without first deleting $XDG_STATE_HOME/nix/profiles/profile

Once you installed a package with nix profile, you get the following error message when using nix-env:

$ nix-env -f '<nixpkgs>' -iA 'hello'
error: nix-env
profile '/home/alice/.local/state/nix/profiles/profile' is incompatible with 'nix-env'; please use 'nix profile' instead

To migrate back to nix-env you can delete your current profile:

Warning

This will delete packages that have been installed before, so you may want to back up this information before running the command.

 $ rm -rf "${XDG_STATE_HOME-$HOME/.local/state}/nix/profiles/profile"
