[Nix-dev] nixos-install building FLAC and failing

[Malcolm Matalka]

I'm trying to install NixOS on another Linode host, and I'm running into
something odd during 'nixos-install'.

Despite my configuration, AFAIK, a bunch of sound stuff is being
installed, and FLAC is failing on tests, most likely because I'm running
as root.  I just don't understand why FLAC is being installed at all.
Here is part of the output from nixos-install showing the deps it still
needs to build.

Here is the error:

Also, I don't seem able to build a dependency graph to see why sound is
begin pulled in because nothing is actually installed yet.

Any suggestions how to debug this?
