Add an option for shell script fragments that are ran before switching
to a new NixOS system configuration (pre installation of bootloader or
system activation). Also add a new subcommand for
switch-to-configuration called "check" that will cause the program to
always exit after checks are ran.
See https://github.com/systemd/systemd/issues/33414.
The way this was phrased sounded like a dumb search/replace operation to
me. This resulted in random parts of my routing being broken (forward
from if X -> Y being fine, but the opposite direction being broken).
This change makes it explicit that it's a little more complicated and
you should really consult the docs before making that change.
Now it's placed between initrd-switch-root.target and
initrd-switch-root.service, meaning it is truly the last thing to
happen before switch-root, as it should be.
Reverts #344407
This has broken nixos-rebuild switch so that it no longer updates the profile, which has bad consequences including not updating the systemd-boot menu with new generations.
Originally, we switched to bsdtar from libarchive to solve a reproducibility issue related to hardlinks
As of gnu cpio 2.14 the --ignore-dirnlink option is introduced and now included in --reproducible, which solves this issue
By switching back, we are in turn solving an issue in libarchive >=3.7.5 erroring out with "Error reading archive -: (null)"

Prior to this contribution, every boot with a default configuration was
considered `ConditionFirstBoot=true` by systemd, since /etc/machine-id
was not commited to disk.
This also extends the systemd with a check for subsequent boots not
being considered first boots.
The perl snippet as been added years ago. I assume the intention was to
remove the `## file: iwlwifi.conf` section up to the next `## file:`,
but as there is no file following, the snippet currently does nothing.
We should be fine to remove it.

Before this change, the hash of the etc metadata image was included in
the mount unit that's responsible for mounting this metadata image in the
initrd.
And because this metadata image changes with every change to the etc
contents, the initrd would be rebuild every time as well.
This can lead to a lot of rebuilds (especially when revision info is
included in /etc/os-release) and all these initrd archives use up a lot of
space on the ESP.
With this change, we instead include a symlink to the metadata image in the
top-level directory, in the same way as we already do for things like init and
prepare-root, and we deduce the store path from the init= kernel parameter,
in the same way as we already do to find the path to init and prepare-root.
Doing so avoids rebuilding the initrd all the time.
When installing NixOS on a machine with Windows, the "easiest" solution
to dual-boot is re-using the existing EFI System Partition (ESP), which
allows systemd-boot to detect Windows automatically.
However, if there are multiple ESPs, maybe even on multiple disks,
systemd-boot is unable to detect the other OSes, and you either have to
use Grub and os-prober, or do a tedious manual configuration as
described in the wiki:
https://wiki.nixos.org/w/index.php?title=Dual_Booting_NixOS_and_Windows&redirect=no#EFI_with_multiple_disks
This commit automates and documents this properly so only a single line
like
boot.loader.systemd-boot.windows."10".efiDeviceHandle = "HD0c2";
is required.
In the future, we might want to try automatically detecting this
during installation, but finding the correct device handle while the
kernel is running is tricky.
systemd 256 supports network.wireguard.* credentials (https://github.com/systemd/systemd/pull/30826).
Check whether PrivateKey / PresharedKey starts with an @, if so it is a credential.
