This provides a more convenient syntax and allows easier overriding.
For example,
environment.etc = singleton
{ target = "vconsole.conf";
source = vconsoleConf;
};
can now be written as
environment.etc."vconsole.conf".source = vconsoleConf;
Adding support for the kind of bootloader in raspberrypi. Disable grub,
disable generationsDir, enable boot.loader.raspberrypi.
Usual layout expected: /boot being the first vfat the board reads blobs from.
If the user tries to run a program that doesn't exist from Bash, the
program name is looked up in a database that maps to Nix package
names. If it is found, we print out a message like:
$ pdflatex
The program ‘pdflatex’ is currently not installed. It is provided by
several packages. You can install it by typing one of the following:
nix-env -i tetex
nix-env -i texlive-core
If the environment variable $NIX_AUTO_INSTALL is set, the command is
installed and executed automatically:
$ hello --version
The program ‘hello’ is currently not installed. It is provided by
the package ‘hello’, which I will now install for you.
installing `hello-2.8'
hello (GNU hello) 2.8

To use this, you must currently manually put the SQLite programs
database in /var/lib/nixos/programs.sqlite. In the future, this file
should be provided as part of the NixOS channel so it gets updated
automatically. To get a test version:
$ curl http://nixos.org/~eelco/programs.sqlite.xz | xz -d > /var/lib/nixos/programs.sqlite
This makes it possible to build several NixOS systems that use different
nixpkgs in the same nix-build invocation. Today, you can't do that since
the <nixpkgs> path reference is hard-coded in lib/eval-config.nix.
This reverts commit 683100666d98f758b4ae3172686633a4840ec1bc.
Seems somebody (systemd? the kernel?) gets confused at power
events and remounts the filesystem containing /nix/store as
read-only.
Commit 37b56574e20755e4c58370bb18a3d373d4ae7cfc revealed that the code
to get regInfo from /proc/cmdline was broken. It only happened to
work because the kernel passes the command line to stage 1 through the
environment, so $regInfo was set anyway.
