nix copy: Add --profile and --out-link flags

Open edolstra opened this issue 1 year ago • 2 comments

Motivation

This allows nix copy to atomically copy a store path and point a profile to it, without the risk that the store path might be GC'ed in between. This is useful for instance when deploying a new NixOS system profile from a remote store.

@fricklerhandwerk I agree, but that's a bit of a general problem beyond the scope of this PR, since currently every MixProfile command has this issue.

What do you mean with "appropriate blurb"?
