Add archinstall to the list of packages thare are installed on the ISO.

README.rst:
Add a "Releases" section that specifies who is creating releases and which PGP key ID is used to sign tags.
Additionally, information about how to retrieve the relevant public key and how to verify a tag in the repository is
added.

Fixes #114

configs/releng/airootfs/etc/xdg/reflector/reflector.conf:
Reduce the amount mirrors that reflector checks from 70 to 20.
This significantly reduces the time it takes to end up with an up-to-date mirrorlist during boot with the releng
profile.

Fixes #92

configs/releng/airootfs/root/.automated_script.sh:
Add the `--location` curl parameter (see `man 1 curl`) to allow for curl to retrieve a remote script even if the source
is being redirected (e.g. moved permanently) when using the `script=` kernel commandline parameter.

Fixes #113

ModemManager's mmcli is the simplest way to connect with WWAN modems.

Mention mmcli in MOTD.

Implements #110.

Add /etc/systemd/network/20-wwan.network

Related to #110.

The file is limited to Wi-Fi (Type=wlan in networkd configuration).

* Match the device type instead of the interface name.
* Replace DHCP section with DHCPv4/DHCPv6. systemd split the sections.

Remove hardcoded '-comp xz', it prevents using mksquashfs defaults.

Fixes #112.

Allow building ISOs with EROFS airootfs images in CI.

Packages with files in /usr/lib/modules/ depend on the current kernel, thus they should not be updated.

- if a folder listed in the associative array ends with a "/",
  recursively apply chmod and chown.

Forks may not have access to secure runners. Restrict build:secure to https://gitlab.archlinux.org/archlinux/archiso/ only.

Fixes archlinux/archiso#106 .

Some mksquashfs runs take a very long time and 1000 seconds might not be enough.

EROFS, like Squashfs, is a read-only file system. It can be used to store airootfs in an image file.
Its advantage is the support for POSIX ACLs. EROFS downside is that currently it only supports LZ4 compression (LZMA support is not yet fully implemented).

A difference from Squashfs is that, EROFS stores change time (ctime) not modification time (mtime). The reverse is true for Squashfs.

Implements #59

Remove /run/archiso/bootmnt directory if nothing is mounted there. An empty directory is just confusing.

configs/releng/packages.x86_64:
Add usbmuxd to list of packages, so that users have the option to use iOS devices out-of-the-box for data connection
during installation.

Fixes #99

haveged was added 8 years ago[1] to increase entropy and presumably to
prevent entropy starvation.

A few things has changed since, most notable:
* the kernel actively tries to add entropy (jitter entropy)[2][3][4][5]
* /dev/random no longer blocks after CRNG initialization[6][7]

Fix #98

`du --block-size=MiB` (and `du -m`) returns mebibytes not megabytes.

Additionally, shorten the du command. `du --block-size=MiB` is the same as `du -m`.

CHANGELOG.rst:
Add file to track changes (at least for v51).

.gitlab/ci/build-host.sh:
Set shebang to /usr/bin/env bash to be more portable/flexible.
Turn all posix statements ([]) to bash style statements ([[]]), as we are using bash.
Terminate the list of parameters to rm or cp with --.

Replace the implementation of finding a local ISO to use with one that relies on a sorted list of potential images.

Use virtio-net-pci for networking with qemu.
Set the cow_spacesize to 4G for the archiso environment.

Use --needed in the call to pacman to not re-install already up-to-date targets.
Attempt a full system upgrade (but ignore the kernel).
Increase the timeout for when installing packages to the archiso environment using pacman to 120s, as a system upgrade
is being done as well.

Use systemctl poweroff -i to shut down the virtual machine as it is more future proof and robust.

.gitlab-ci.yml:
Add a build stage to the gitlab CI, that facilitates the scripts below .gitlab/ci/, building the baseline and releng
profiles in parallel.
Distinguish the use-case in which builds are done for master, schedules and tags in a secure environment and any other
where builds just have to be fast (for ensuring nothing is broken).

Use MiB as block size for the du call when generating data for the metrics file.

Makefile:
Add scripts below .gitlab/ci/ to the lint target of the Makefile.

.gitlab/ci/build-host.sh:
Add script to be run in a container with access to qemu.
It is a slight modification of arch-boxes' build-host.sh script to cater to the specific archiso requirements.

.gitlab/ci/build-inside-vm.sh:
Add script to be run in virtualized environment, established by build-host.sh.
This script builds the actual archiso profiles and creates checksum for the resulting image files.

This finally removes customize_airootfs.sh from releng.

Fixes #21 .

This works around https://bugs.archlinux.org/task/49347 .
Leaving the hooks in the airootfs image will result in it being run when pacstrap is run in the live environment. This should not happen as they are intended for the ISO build process only.

Fixes #91 .

- Apply overrides before validating the options.
- Parse all paths with realpath. Fixes #84 .

configs/releng: move the mirror uncommenting sed command from customize_airootfs.sh to a pacman hook

After pacman-mirrorlist is installed, /etc/pacman.d/hooks/uncomment-mirrors.hook will run a sed command which uncomments all Server lines in /etc/pacman.d/mirrorlist.
This brings us another step closer to the complete removal of customize_airootfs.sh.

Booting via PXE we want to keep our DNS configuration. So remove
/etc/resolv.conf in new root before copying the current file.

Without this systemd-resolved fallback nameservers are used and we see an
error message when the root ships a symbolic link to systemd-resolved's
stub-resolv.conf:

cp: not writing through dangling symlink '/new_root/etc/resolv.conf'

To date the iso version was used for iso volume information and iso file name.
In my custom builds I do use it a lot more:

* Inside the root fs: The system knows about its own version. I use this to:
  -> report the version to a server (poor man's inventory)
  -> let the system update itself

* On the iso fs: The files are served via rsync, running systems transfer
  version file first to check for available update.

* A grub environment file on the iso fs: Booting the iso from grub allows
  to create cow directory per version:

    loopback loop archlinux.iso
    load_env -f (loop)/arch/grubenv
    linux (loop)/arch/boot/x86_64/vmlinuz-linux ... \
        cow_directory=archlinux/${VERSION} ...

So let's just create these files.
