The NixOS repository from which the system will be built.
|
|
<command>nixos-checkout</command> will update all working
|
|
copies of the given repositories,
|
|
<command>nixos-rebuild</command> will use the first item
|
|
which has the attribute <literal>default = true</literal>
|
|
falling back to the first item. The type defines the
|
|
repository tool added to the path. It also defines a "valid"
|
|
repository. If the target directory already exists and it's
|
|
not valid it will be moved to the backup location
|
|
<filename><replaceable>dir</replaceable>-date</filename>.
|
|
For svn the default target and repositories are
|
|
<filename>/etc/nixos/nixos</filename> and
|
|
<filename>https://svn.nixos.org/repos/nix/nixos/trunk</filename>.
|
|
For git repositories update is called after initialization
|
|
when the repo is initialized. The initialize code is run
|
|
from working directory dirname
|
|
<replaceable>target</replaceable> and should create the
|
|
directory
|
|
<filename><replaceable>dir</replaceable></filename>. (<command>git
|
|
clone url nixos/nixpkgs/services</command> should do) For
|
|
the executables used see <option>repoTypes</option>.
