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.

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.

file path
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.

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 https://gitlab.archlinux.org/archlinux/archiso/-/issues/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).

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.

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.

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.
