After the change from revision 30103, nixos-rebuild suddenly consumed freaky amounts of memory. I had to abort the process after it had allocated well in excess of 30GB(!) of RAM. I'm not sure what is causing this behavior, but undoing that assignment fixes the problem. The other two commits needed to be revoked, too, because they depend on 30103. svn path=/nixos/trunk/; revision=30127

The configuration of the Nix Packages collection. (For

details, see the Nixpkgs documentation.) It allows you to set
|
|
package configuration options, and to override packages
|
|
globally through the <varname>packageOverrides</varname>
|
|
option. The latter is a function that takes as an argument
|
|
the <emphasis>original</emphasis> Nixpkgs, and must evaluate
|
|
to a set of new or overriden packages.

Specifies the Nix platform type for which NixOS should be built.
|

If unset, it defaults to the platform type of your host system
|
|
(<literal>${builtins.currentSystem}</literal>).
|
|
Specifying this option is useful when doing distributed
|
|
multi-platform deployment, or when building virtual machines.
