- Added a backdoor option to the interactive run-vms script. This allows me to intergrate the virtual network approach with Disnix
- Small documentation fixes
Some explanation:
The nixos-build-vms command line tool can be used to build a virtual network of a network.nix specification.
For example, a network configuration (network.nix) could look like this:
{
test1 =
{pkgs, config, ...}:
{
services.openssh.enable = true;
...
};
test2 =
{pkgs, config, ...}:
{
services.openssh.enable = true;
services.xserver.enable = true;
}
;
}
By typing the following instruction:
$ nixos-build-vms -n network.nix
a virtual network is built, which can be started by typing:
$ ./result/bin/run-vms
It is also possible to enable a backdoor. In this case *.socket files are stored in the current directory
which can be used by the end-user to invoke remote instruction on a VM in the network through a Unix
domain socket.
For example by building the network with the following instructions:
$ nixos-build-vms -n network.nix --use-backdoor
and launching the virtual network:
$ ./result/bin/run-vms
You can find two socket files in your current directory, namely: test1.socket and test2.socket.
These Unix domain sockets can be used to remotely administer the test1 and test2 machine
in the virtual network.
For example by running:
$ socat ./test1.socket stdio
ls /root
You can retrieve the contents of the /root directory of the virtual machine with identifier test1

{
test1 = {pkgs, config, ...}:
{
# NixOS config of machine test1
...
};
test2 = {pkgs, config, ...}:
{
# NixOS config of machine test2
...
};
}
And an infrastructure expression, e.g:
{
test1 = {
hostName = "test1.example.org";
system = "i686-linux";
};
test2 = {
hostName = "test2.example.org";
system = "x86_64-linux";
};
}
And by executing:
nixos-deploy-network -n network.nix -i infrastructure.nix
The system configurations in the network expression are built, transferred to the machines in the network and finally activated.

installation CD.
The configuration file, which is generated by nixos-hardware-scan, enables
not-detected devices by default.

init script. This removes the need for the `systemConfig' boot
parameter; `init=<stage-2-init>' is enough. However, the GRUB menu
builder still needs to add `systemConfig' to the kernel command line
for compatibility with old configurations.

like `build-vm', but boots using the regular boot loader (i.e. GRUB
1 or 2) rather than booting directly from the kernel/initrd. Thus
it allows testing of GRUB.

we want to generate the GRUB menu without actually installing GRUB
(because Amazon supplies its own pv-grub), and each menu entry
requires "root (hd0)". For the first, allow boot.loader.grub.device
to be set to "nodev" to indicate that the GRUB menu should be
generated without installing GRUB. For the second, add an option
boot.loader.grub.extraPerEntryConfig to allow commands to be added
to each GRUB menu entry (in this case, "root (hd0)").

grub.cfg before the menu entries. (This could also be done using
`extraEntriesBeforeNixOS', but then you can't have entries *after*
the main entry anymore.)
* In the installer test, redirect GRUB output to the serial port.

What I want with this derivation is to allow the sheevaplug nixos to
build a tarball with all the needed files to boot. Then, this can be
unpacked into an SD card, or into a NFS/TFTP server, and then the
user can boot the system with help of the uboot console.
By now, I have only tried to build the tarball in a PC, in order
to develop the nix expressions quicker.
There is nothing written specialy for the Sheevaplug in all this,
by now.

is done by instantiating a webserver that simulates nixos.org.
Using nix-push we create a channel that contains some stuff (namely
the GNU Hello source tarball and the rlwrap program). This was a
bit tricky because nix-push requires a writable Nix store. Using
AUFS this is possible, but not on recent Linux kernels (AUFS1 over
CIFS fails).

partition from /. If so, copy the kernels and initrds to /boot and
use paths relative to /boot in the GRUB configuration file. This
makes the boot.loader.grub.bootDevice option obsolete. (Is there a
way to mark obsolete options?) It also makes it unnecessary to set
boot.loader.grub.copyKernels, although that option is still
available since it can speed up GRUB if the Nix store is very
large.

GRUB version changes. (That's the complete version from the name
attribute, not the boot.loader.grub.version attribute.) The current
version is recorded in /boot/grub/version. This is required to
prevent massive breakage when we change the default value of
boot.loader.grub.version to "2".

modules that should be added to the initrd, but should only be
loaded on demand (e.g. by the kernel or by udev). This is
especially useful in the installation CD, where we now only load the
modules needed by the hardware.
