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

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.

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

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

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 .

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.

Related to #21 .

See https://lists.archlinux.org/pipermail/arch-devops/2020-December/000474.html .

Fixes https://bugs.archlinux.org/task/68803 .

archiso/mkarchiso:
Make sure to always compare absolute paths in `_make_custom_airootfs()` (as `realpath` is used).
Remove `echo` calls that prevent the setting of actual file ownerships and modes.

configs/releng/profiledef.sh:
Set file mode of /root/.automated_script.sh to 755.

Fixes #82

This gets rid of the duplicate ldlinux.c32 and the useless isolinux.cfg which only points to syslinux.cfg.

Implements #46 .

profiledef.sh can now contain an associative array called file_permissions which can be used to set custom ownership and mode of custom airootfs files. The array's keys contain the path and the value is a colon separated list of owner UID, owner GID and access mode.
For example:

    file_permissions=(
      ["/etc/shadow"]="0:0:400"
    )

This means that mkarchiso now copies airootfs files (and directores) without permissions and anything that should be owned by a user other than root and/or if the mode should be something other than 644 for files and 755 for directories must to be listed in ${file_permission[@]} in profiledef.sh.

Fixes #61 .

Default: 732M
With these options: 675M

- fatresize is a utility to resize FAT filesystems using libparted.
- gpart is partition table rescue/guessing tool.
- tmux is a terminal multiplexer. Requested in https://bugs.archlinux.org/task/68252 .

configs/releng/syslinux/archiso_sys.cfg:
Set the syslinux bootloader timeout to 15s.
In !97 it has accidentally been set to 1.5s.

configs/releng/efiboot/loader/loader.conf,
configs/releng/syslinux/archiso_sys.cfg:

Set the bootloader timeout to 15s, as they have been set to an overly generous 30s in !79.

Fixes #80

configs/releng/airootfs/usr/local/bin/livecd-sound:
Replace oldstyle expr with a bash test in `is_numeric()`.

Replace use of `nword()` with call to `wc -w`.

Quote variables in `pick_a_card()`.

Fixes #78

this fixes #67

The default mkinitcpio.conf includes modconf in HOOKS.

- squashfs-tools can be used for system backup. https://wiki.archlinux.org/index.php/Full_system_backup_with_SquashFS
- udftools is needed to format UDF file systems.

configs/{baseline,releng}/build.sh:
Remove `build.sh` scripts. They were deprecated with v47.

archiso/mkarchiso:
Remove all `build.sh` related functionality (i.e. `command_pkglist()`, `command_iso()`, `command_prepare()`,
`command_install()`, `command_init()`, `command_run()`).

Rename `command_build_profile()` to `_build_profile()` to be more in line with the style of the other function naming.

Change `_show_config()` to only print info about the profile and make no more use of parameters.

Remove all help output related to legacy `build.sh` commands.

Fixes #51

Slightly simplifies adding boot loader configuration for more kernels.
Unfortunately the INCLUDE statement doesn't support wildcards, so each new file must be manually included in the main syslinux configuration file (syslinux.cfg for baseline and archiso_sys.cfg for releng).

This allows to use only one systemd-boot configuration file per kernel.
Fixes archlinux/archiso#44 .

This is a breaking change. archweb, archiso-manager and various documentation must be updated.

* https://github.com/archlinux/archweb/blob/master/templates/releng/archlinux.ipxe
* https://github.com/pierres/archiso-manager/blob/master/Makefile

archiso specific options are placed in a /etc/systemd/system/reflector.service.d/archiso.conf drop-in.

**archiso/mkarchiso**:

Change all override option parameters (i.e. `-A`, `-C`, `-D`, `-L`, `-P` and `-g`) to not directly override the global
variable they are tied to, but instead using an `override_` prefixed variable.

Add `_set_overrides()` to use `override_` prefixed variables (if set) to override those without a prefix.

Remove `-B` (a profile directory) from the list of parameters. The profile directory is now provided as separate
non-option parameter.

Add a call to `_read_profile()`, `_set_overrides()` and `command_build_profile()` to the fallthrough option of the
switch-case checking `command_name` - a non-option parameter to mkarchiso. This effectively provides the possibility to
set the profile directory using a non-option parameter, while still maintaining compatibility to legacy named arguments
used in the configs' `build.sh` scripts.

Extend the warning in regards to legacy `build.sh` based commands to mkarchiso by providing an EOL with archiso v49.

Change the help output to reflect the changes and further elaborate on the legacy commands used by `build.sh` scripts.

Change help output to be ordered alphabetically.

Add help output for `-r` and `-g` options.

Call `_set_overrides()` for legacy commands that accept one or more of the overriden options (i.e. `command_init`,
`command_install`, `command_prepare` and `command_iso`).

Various style fixes.

**configs/{baseline,releng}/build.sh**:

Change call to mkarchiso to use the profile's directory as a named argument instead of an option-argument.

**README.rst**:

Fix documentation on how to call mkarchiso with a profile directory.

Fix wording and ordering of option arguments for run_archiso documentation.

Fixes #52

Fixes archlinux/archiso#42 .

Replace build.sh scripts with calls to mkarchiso -B "profiledir" build_profile.

Fixes archlinux/archiso#37 .

Boot mode names are:

- bios_syslinux.mbr: SYSLINUX in MBR
- bios.syslinux.eltorito: SYSLINUX (ISOLINUX) via El Torito
- uefi-x64.systemd-boot.esp: systemd-boot on ESP in MBR
- uefi-x64.systemd-boot.eltorito: systemd-boot on ESP via El Torito

It is not yet possible to create an ISO with only El Torito or only MBR boot modes!
