Usage: Launch run_archiso.sh -v ..., and then use a VNC viewer
(e.g. from https://wiki.archlinux.org/index.php/List_of_applications/Internet#Remote_desktop)
to connect (typically to `localhost`) on the default VNC port (5900).

This enables using run_archiso in a "headless" session; e.g. when SSH logged in
to the CLI of a VM, without a local display attached.  This is handy e.g. when
playing https://en.wikipedia.org/wiki/Inception and running an archlinux*.iso
on any non-Arch (say Fedora workstation), on which one built a new ISO, that you
then "run_archiso", inside which you could build another ISO, which you could
itself start inside the nested VM... ;-)

Jokes apart, this could also be used to run automated CI/CD tests of the built ISO,
which is particularly interesting in combination with the cloud-init support;
see https://wiki.archlinux.org/index.php/Cloud-init.

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 .

archiso/mkarchiso:
Guard the call to `_mksignature()` in `_prepare_airootfs_image()` by an if statement.
Using the `&&` logic leads to `_prepare_airootfs_image()` evaluating to false if `$gpg_key` is not set.

Add `_msg_info()` calls to `_set_override()` which prevent the function from evaluating to false if no override is
being done. Additionally this is great for debugging purposes.

Add `_msg_info()` calls to `_read_profile()` (which is great for debugging purposes).

Fixes #81

mkarchiso: add xorrisofs options from boot mode specific functions instead of hardcoding them in _build_iso

Fixes archlinux/archiso#76 .

- Remove remnants of the now removed legacy commands.
- Improve readability by getting rid of some "if" statements when performing string comparisons.
- Rename functions to make their purpose more clear.
- Move some conditions from functions to their invocations.

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

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.
