CHANGELOG.rst:
Add changelog entries for v58.

* nl6720/fix-unbound-variables-in-_validate_options:
  mkarchiso: error out of iso and netboot build modes if no boot modes are specified
  mkarchiso: split out build mode specific checks from _validate_options to _validate_requirements_buildmode_*
  mkarchiso: fix unbound variable errors in _validate_options

mkarchiso: split out build mode specific checks from _validate_options to _validate_requirements_buildmode_*

The bootstrap build mode does not use packages.${arch}, ${bootmodes[@]} or $airootfs_image_type so there's no need to validate them.
Requirements common to iso and netboot are checked with the _validate_common_requirements_buildmode_iso_netboot function.

Fixes #149.

* Rename _validate_requirements_buildmode_all to _validate_common_requirements_buildmode_all to prevent potential conflicts since we are using _validate_requirements_buildmode_${_buildmode} to run the functions.
* Improve searching in an array. See https://stackoverflow.com/a/15394738.

$pkg_list_from_file and $bootstrap_pkg_list_from_file are arrays, they must be referenced as such. Fixes https://bugs.archlinux.org/task/71852.

Remove quotes from arithmetic expressions.

* nl6720/gpg-sender:
  .gitlab/ci/build_archiso.sh: use mkarchiso's -G option
  mkarchiso: support setting gpg sender
  mkarchiso: add some sane gpg options to override those set in user's gpg.conf

Set gpg's --sender.

Add new -G option to set gpg's --sender. This allows to see who signed the rootfs image without needing to import the gpg key from the keyring in initramfs.

* Add --batch, since gpg is run in a script.
* Add --no-armor (this is the default). Armored output provides no benifit here.
* Add --no-include-key-block (this is the default). There is no need to have the gpg key in the signature. The mkinitcpio hook will verify the signature against the included keyring.

Remove the output files before running gpg. Otherwise gpg --batch will fail if they exist.

* nl6720/openssh-8.7p1:
  configs/*/airootfs/etc/ssh/sshd_config: update to openssh 8.7p1-1

Update /etc/ssh/sshd_config to match upstream changes.
The only modification remains "PermitRootLogin yes".

* nl6720/netboot-version:
  mkarchiso: put version files in netboot artifacts

Fixes #147.

* nl6720/no-mount:
  mkarchiso: ensure there are no existing image files before trying to create them
  mkarchiso: copy files to ext4 image using mkfs.ext4's -d option instead of mounting the file system

This could prevent a few issues when creating an image file when re-running mkarchiso after a failure.

Remove useless test before running rm -f. The command will always succeed.

mkfs.ext4 with its -d option can "copy the contents of the given directory into the root directory of the filesystem".
This allows to get rid of the last directly used mount and umount commands in mkarchiso.

Additionally try to make the ext4 image somewhat reproducible by setting E2FSPROGS_FAKE_TIME to SOURCE_DATE_EPOCH, clearing the UUID and using a reproducible hash seed.
See https://git.kernel.org/pub/scm/fs/ext2/e2fsprogs.git/commit/?id=e1f7100643a46456be107b33098f6034b0835e6d .

Place mkfs.ext4 options in an array to avoid duplicating the command.

Related to #40.

* issues/47:
  gitlab-ci: Call renamed check target
  Makefile: Remove mkinitcpio-archiso specific targets

Remove all code specific to mkinitcpio-archiso.
Allow overriding PREFIX (defaults to /usr/local).
Gather scripts to check more generically.
Add abstractions for installation directories.

* changelog/57:
  Add changelog for 57

CHANGELOG.rst:
Add an entry for v57.

* issues/143:
  mkarchiso: Do not run _build_iso_base once

archiso/mkarchiso:
Do not run `_build_iso_base` with `_run_once`, as it sets variables which are important to functions that are called
after it.

* issues/117:
  Remove SPDX license identifier from releng configs
  Remove SPDX license identifier from releng configs

configs/baseline/*:
Remove the SPDX license identifier comment from the configuration files in the profile, as they are not eligible for
copyright.

configs/releng/*:
Remove the SPDX license identifier comment from the configuration files in the profile, as they are not eligible for
copyright.

* nl6720/bootmodes-2:
  mkarchiso: improve functions and comments

* Merge _make_efi_dir_on_iso9660 into _make_bootmode_uefi-x64.systemd-boot.eltorito since it's specific to that boot mode.
* Split off FAT image creation into _make_efibootimg, so it can be reused by other functions.
* Add/improve comments to better document what the script does.

* nl6720/RouteMetric:
  configs/*/airootfs/etc/systemd/system/systemd-networkd-wait-online.service.d/wait-for-only-one-interface.conf: document why the drop-in file exists
  configs/releng/airootfs/etc/systemd/network/: move RouteMetric= from [DHCPv6] to [IPv6AcceptRA]

configs/*/airootfs/etc/systemd/system/systemd-networkd-wait-online.service.d/wait-for-only-one-interface.conf: document why the drop-in file exists

Related to #142.

Add missing `ExecStart=` to baseline's /etc/systemd/system/systemd-networkd-wait-online.service.d/wait-for-only-one-interface.conf.

systemd moved the option. See https://github.com/systemd/systemd/commit/8ebafba9f987c21aa5787c8767f2e390b4ec0bc5 .
Implements #123.

Document in comments why the route metrics need to be set (because of https://github.com/systemd/systemd/issues/17698 ) and use the same metric values as NetworkManager. https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/blob/main/src/core/devices/nm-device.c

Additionally remove RouteMetric from configs/baseline/airootfs/etc/systemd/network/20-ethernet.network.
There is only one networkd configuration file in baseline, meaning, there are no other routes.

* changelog/56.1:
  Add changelog for 56.1

CHANGELOG.rst:
Add a changelog entry for 56.1

* nl6720/LC_ALL:
  mkarchiso: set LC_ALL instead of LANG

LC_ALL overrides LANG and all LC_* variables, so use it instead.
See https://www.gnu.org/software/gettext/manual/html_node/Locale-Environment-Variables.html#Locale-Environment-Variables .

* nl6720/releng-remove-package-termite-terminfo:
  configs/releng/packages.x86_64: remove termite-terminfo
