This also makes configuration available if you just run those tools locally.
Also use ruff instead of pylint because it's faster and more
comprehensive.
Since 008f9f0cd4
("nixos/test-driver: actually use the backdoor message to wait for backdoor"),
when boot is still computering, we can get a tons of empty strings in response to the shell.
This is not really useful to print and waste the disk space for any CI system that logs them.
We stop logging chunks whenever they are empty.
While working on #192270, I noticed that only some wait_for_* helper
functions make the timeout configurable. I think we should be able to
customize it in all cases
https://git.sr.ht/~c00w/nixpkgs/tree/sdimagebtrfs/item/nixos/lib/make-btrfs-fs.nix
I made only one change which was to use `btrfs check` instead of
`fsck.btrfs` because of this warning
```
btrfs-fs.img> ++ fsck.btrfs /nix/store/6d46rc768c140asy6rjpc5rk568r36zq-btrfs-fs.img
btrfs-fs.img> If you wish to check the consistency of a BTRFS filesystem or
btrfs-fs.img> repair a damaged filesystem, see btrfs(8) subcommand 'check'.
```

This commit is a fixup for a regression introduced by
0bdba6c99b.
Before the regression, it was possible to build images without grub or a
kernel (e.g. to boot other kernels with qemu -kernel.
After the regression, such images fail to build. Since
config.boog.loader.grub.enable is false in that scenario, grub.device is
emptystring. While this happens not to be an issue of `ln`, `dirname`
fails on emptystring.
With this change, we guard both commands to only be run when grub is
actually enabled. Images with and without grub succesfully build with
this change.
New EDK2 sets up the backdoor port as a serial console, which feeds the test driver
a bunch of boot logs it can safely ignore. Do so by waiting for the message the
backdoor shell prints before doing anything else.
According to systemd.netdev manpage:
```
MACAddress=
Specifies the MAC address to use for the device, or takes the special value "none". When "none", systemd-networkd does not request the MAC address for
the device, and the kernel will assign a random MAC address. For "tun", "tap", or "l2tp" devices, the MACAddress= setting in the [NetDev] section is
not supported and will be ignored. Please specify it in the [Link] section of the corresponding systemd.network(5) file. If this option is not set,
"vlan" device inherits the MAC address of the master interface. For other kind of netdevs, if this option is not set, then the MAC address is
generated based on the interface name and the machine-id(5).
Note, even if "none" is specified, systemd-udevd will assign the persistent MAC address for the device, as 99-default.link has
MACAddressPolicy=persistent. So, it is also necessary to create a custom .link file for the device, if the MAC address assignment is not desired.
```
Therefore, `none` is an acceptable value.
When lib overrides were used, before this commit, they would not be made
available in the configuration evaluation of nixosTest's nodes.
Sample code:
``` nix
let
pkgs = import ./. {
overlays = [
(new: old: {
lib = old.lib.extend (self: super: {
sorry_dave = builtins.trace "There are no pod bay doors" "sorry dave";
});
})
];
};
in
pkgs.testers.nixosTest {
name = "demo lib overlay";
nodes = {
machine = { lib, ... }: {
environment.etc."got-lib-overlay".text = lib.sorry_dave;
};
};
testScript = { nodes }:
''
start_all()
machine.succeed('grep dave /etc/got-lib-overlay')
'';
}
```
By some miracle, before, it was possible to reconnect to the `node1` without
doing any relevant dance.
But now we are direct booting (¿), it seems like we need to do the right things.
This introduces a `check_output` flag for `execute` because we do not want to steal the
messages from the backdoor service as we might execute the kexec too fast compared
to when we will reconnect.
Therefore, we will let the message in the pipe if needed.
