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

scripts/run_archiso.sh:
Add the `-a` option flag to add accessibility support on demand for `run_archiso`.

Add accessibility specific options to qemu in `run_image()`.

Not providing the specific braille chardev hardware otherwise blocks running run_archiso with
`qemu-system-x86_64: -chardev braille,id=brltty: brlapi__openConnection: connect: No such file or directory`.

Fixes #77

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

README.profile.rst:
Add information on all necessary components of a profile:

* profiledef.sh
* packages.arch
* airootfs/
* efiboot/
* isolinux/
* syslinux/

Fix wording for pacman.conf documentation

README.rst:
Add a link to README.profile.rst.

Fixes #38

forgot to enable USB support.

necessary for testing brltty in archiso

archiso/mkarchiso:
Change `_pacman()` to use the *modified* pacman.conf from the work_dir, instead of using the *unmodified* pacman.conf from
the profile.

Change `_make_pacman_conf()` to compare the system's and the profile's CacheDir setting and use the profile's CacheDir
setting only if it's not the default and not the same as the system's.

Always set the HookDir to the airootfs' override directory, so that no hooks from the host system are being run.

Remove DBPath, LogFile and RootDir settings from the work_dir pacman.conf as they are otherwise referring to the host
system, **even if** pacman is being called with the `-r` flag.

Fix a typo in _make_custom_airootfs().

README.profile.rst:
Add information about the pacman.conf in a profile and how configuration options behave, when used by mkarchiso.

Fixes #73
Fixes #74

Support bios.syslinux.eltorito boot mode without bios.syslinux.mbr.
bios.syslinux.mbr does not work without bios.syslinux.eltorito because -isohybrid-mbr requires the El Torito boot image.

Support uefi-x64.systemd-boot.esp boot mode without uefi-x64.systemd-boot.eltorito and vice versa.
If uefi-x64.systemd-boot.eltorito is used without uefi-x64.systemd-boot.esp, the El Torito boot image will be placed in the ISO 9660 file system as before.
Note that an ISO created with only uefi-x64.systemd-boot.eltorito will still be bootable as a "hard disk" on OVMF. OVMF will boot the El Torito image.

This change has the following effect on the partition tables:

- *.eltorito options add El Torito boot catalog entries. MBR and GPT are not affected.
- uefi-x64.systemd-boot.esp creates a protective MBR partition table and a GPT table that includes a Linux filesystem data partition for the ISO 9660 volume, an EFI system partition and a Microsoft basic data partition that maps the 300 KiB padding added by xorriso.
- bios.syslinux.mbr (without uefi-x64.systemd-boot.esp): adds a MBR partition table and maps the ISO 9660 volume as a partition of type 0x83. No GPT is produced.
- bios.syslinux.mbr (with uefi-x64.systemd-boot.esp): adds an second partition in the MBR (after 0xEE) starting from sector 0 to sector 1 with type 0 and marks it as bootable. This violates the GPT specification, but allows some systems to succesfully boot in BIOS mode from GPT.

Fixes #49

also included serial output on stdio it helps in debugging without sight.

README.rst:
Add Contribute section to README to provide information about code of conduct, contributing guide and contact
information (mailing list and IRC).

Fixes #72

Remove efiboot.img if it exists so that mkfs.fat does not fail.

Print the build date.
Don't re-run mksquashfs if it succeeded, but the failure was in gpg signing. For example, if the gpg pinentry timed out.

Check command line parameter count instead of option count, and do it after evaluating option arguments

Fixes b6241cb1 .

Check if a profile or command is specified before looking at EUID.

archiso/mkarchiso:
The bash arithmethics in _make_boot_uefi-x64.systemd-boot.esp() introduced rounding issues, that can lead to
insufficient FAT image size for the files.
Conversion functions for awk now replace the bash arithmetics and additionally a ceil() function rounds the calculated
size up to the next full MiB.
Add an info message about the size of the created FAT image.

Fixes #70

archiso/mkarchiso:
Change the way _show_config() displays information about the build environment, as displaying a profile directory as a
legacy command to mkarchiso is confusing.
The function now prints a deprecation message if '$command_name' is not a directory (i.e. not a profile).
Remove 'command_' prefix from help output for legacy commands (the prefix is only in use for internal functions).

Relates to !69
Fixes #60

Use du to count the file size of the kernel(s), initramfs images and boot loader (and its configuration).
This allows to compress initramfs with something other than xz, or have more than one kernel installed.

Fixes #62 .

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).

All kernels and initramfs images from airootfs are copied to ${install_dir}/boot/ on both ISO 9660 and FAT.
This allows providing multiple kernels. The kernel package needs to be added to packages.x86_64 and the boot loader configuration files created/adjusted appropriately.

Support all possible microcode initrd file names.

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.

Copy /etc/skel/ only for users with UID in range 1000–60000.
Correct user home directory permission after copying files.
Fixes all /etc/skel issues from https://bugs.archlinux.org/task/67729 .

- mtools supports SOURCE_DATE_EPOCH.
- The image file is operated on directly instead of mounting the file system. This is a prerequisite to limit the commands that run with root privileges. Related to #40 .
- Add a reminder comment to not get rid of the dosfstools dependency, since a mformat made FAT image can fail to boot on some systems.

**archiso/mkarchiso**:

In d90184a7 the unbound variable `override_install_dir` was introduced by accident.

It is required to be set to empty string to provide override functionality for `install_dir`.

Fixes #57

**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}".
