**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 to issues introduced in archlinux/archiso!59 :
- _make_boot_on_fat(): copy initramfs from "${airootfs_dir}/boot/" not "${isofs_dir}/". Otherwise UEFI-only ISOs cannot be built.

Some general fixes:
- Replace mkdir with install. Unlike mkdir, install does not complain when the target exists.
- Reduce excess newlines produced by messages.
- Ensure FAT image gets unmounted in case the script is interrupted.
- Create the ext4 image with mkfs.ext4 instead of truncate.
- Do not rely on user and group names for chown commands. Use numeric UID and GID instead.
- Minimize the times stderr is redirected to /dev/null.
- Add missing '?' to getopts.
- Standardize function definitions by removing spaces between the function name and () .

Use "${airootfs_dir}".
Fixes a mistake introduced when rebasing !64 .

Joliet ensures correct file names capitalization on operating systems that support Joliet but not support Rock Ridge.
Implements #45 .

Fixes archlinux/archiso#42 .

Use virtio-scsi to attach the image. virtio-blk (if=virtio) is inconsistent about the used media type.

ISO testing doesn't require the emulated firmware's PXE stack.
For UEFI, it only disable iPXE in favor of EDK II network stack. https://github.com/tianocore/tianocore.github.io/wiki/EDKII-Network-Over-QEMU#verification-result

Various bash script improvements.

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

Fixes archlinux/archiso#37 .

There is nothing useful in /boot for the live system.

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!

Adapt _make_* functions to mkarchiso.

Related to #37 .

Nothing is implemented yet!

configs/releng/profiledef.sh:
A test profile.

Quote all variables.
Terminate option processing using '--' for commands that support it.
Do not hardcode file descriptor.
Compare integers with arithmetic comparison instead of string comparison.
Replace echo with printf.
Use heredoc for usage text.
Don't print INFO messages when quiet is set.
Export SOURCE_DATE_EPOCH.

exfatprogs uses the kernel's driver unlike exfat-utils which provides a FUSE driver.

An ISO's checksum and GPG validation primarily matters when PXE booting, so it would be appropriate to enable these options for releng.
They should protect against booting a corrupt image.

Apparently blockdev does not support it.
In an ISO made using '-s img' (Squashfs with dm-snapshot), it results in:

    blockdev: Unknown command: --

archiso/mkarchiso:
Add the -rational-rock option to xorriso.
This is a preparatory step for creating ISOs as a regular user. See #40 .

Fixes archlinux/archiso#35 .

Properly track the file instead of modifying it on-the-fly with customize_airootfs.sh.
See #21 .

`make check` could get extended to include other things besides just linting.

Makefile:
Move shellcheck to a "lint" target and change "check" so that it runs "lint".
This provides a more finer grained control and allows to extend "check" with things beyond just linting.

.gitlab-ci.yml:
Run `make lint` in the lint job.

configs/releng/airootfs/etc/systemd/system/reflector.service:
Use the 70 mirrors synced most recently (--latest) instead of a specific time since last sync (--age).
According to FS#67399 using 1hour as sync age is too short, as it sometimes leads to empty list.

They are not required in the host system. See #34 .

Place custom mkinitcpio.conf in airootfs.
Use a custom mkinitcpio preset to specify generated image file path.

configs/releng/airootfs/etc/fstab:
/etc/fstab shipped by the filesystem package has only comments. There is no reason to replace it with an empty file.

configs/releng/airootfs/etc/systemd/system/default.target:
There is no harm in booting to graphical.target. releng does not enable (or even install) any service that has {Required,Wanted}By=graphical.target.

Gets rid of a gpg warning:
gpg: WARNING: unsafe permissions on homedir '/tmp/mkinitcpio.*/root/gpg'

LICENSE:
Add GPL-3.0 license.

{{archiso,configs}/*,.editorconfig,.gitlab-ci.yml}:
Add SPDX license identifier.

Makefile:
Add SPDX license identifier.
Install the `run_archiso.sh` script as global executable `run_archiso`.
Use -D and -t flags to install to install files more generically (without a previous call to install the directory).

README.rst:
Add README outlining the project's scope, how to build images from the profiles and how to test.

AUTHORS.rst:
Add list of all direct contributors to the repository.

CONTRIBUTING.rst:
Add basic contribution guidelines, explaining the linter and the license in use.

Closes #7
Closes #3

configs/*:
Copy all files that do not need a rename generically (not specifying a destination file name).
Do not rename vmlinuz-linux to vmlinuz or vmlinuz.efi (as this serves no purpose and makes the scripts more
complicated).
Do not rename microcode (i.e. {amd,intel}-ucode.img) when copying them and change all boot loader configuration files
that assume a renamed microcode image.
Add note and link to Arch Linux wiki to state why memtest.bin is renamed to memtest.
Copy license files for {amd,intel}-ucode and memtest more generically by placing them into subdirectories with the same
name as the package (to circumenvent overwriting one other).

Closes #33

Additionally copy the files to all custom user homes, not just root's.

Show a deprecation notice if airootfs/root/customize_airootfs.sh is found.

configs/{baseline,releng}/build.sh:
Copy custom files to airootfs before installing packages.
Instead of calling `mkarchiso init`, list all required packages in packages.x86_64 and install them all at once with `mkarchiso install`. The mkdir command which `mkarchiso init` performs is now done by make_custom_airootfs.

configs/releng/build.sh:
Don't copy configs/releng/pacman.conf to airootfs, it is only meant to provide a unmodified pacman.conf durring pacstrap. In airootfs, an unmodified /etc/pacman.conf will be installed with the pacman package.

Install linux and mkinitcpio packages.
Remove root user's password.

Fixes https://bugs.archlinux.org/task/64236 .

Correct shadow file permissions from build.sh.

This reverts commit 2993b808.

Actions are disabled in archiso's GitHub mirror.

Having a shellcheck directive and custom comments in the same line can trigger SC1107 on old versions of shellcheck.

.github/workflows/lint.yml:
Run `make check`.
