erofs-utils 1.4 introduced a --quiet option.
Related to #148.
|
|
mksquashfs supports a -quiet option since squashfs-tools 4.4.
Use this option in non-verbose mode instead of redirecting stdout of the whole command to /dev/null.
This allows to have only one instance of mksquashfs in _run_mksquashfs instead of multiple ones in if-then-else.

Only the total size is relevant.

The output is irrelevant, we only need the return code.
Related to #148.
|

The `xorriso -as mkisofs` option `-quiet` is interpreted too late. Use native xorriso option `-report_about SORRY` instead and ensure it is the first option.
Related to #148.

mkfs.fat does not have a -q/--quiet option, so redirect its stdout to /dev/null instead.

netboot does not need any of the boot loaders or their files.
Fixes #150.
|

printf is a bash builtin, so by using it an external command can be avoided.
Due to the differences between date(1) and strftime(3), the time zone output will not contain a colon anymore. Fortunately, that is still a supported format according to https://en.wikipedia.org/wiki/ISO_8601#Time_offsets_from_UTC .

_validate_requirements_buildmode_*
The bootstrap build mode does not use packages.${arch}, ${bootmodes[@]} or $airootfs_image_type so there's no need to validate them.
Requirements common to iso and netboot are checked with the _validate_common_requirements_buildmode_iso_netboot function.
Fixes #149.
* Rename _validate_requirements_buildmode_all to _validate_common_requirements_buildmode_all to prevent potential conflicts since we are using _validate_requirements_buildmode_${_buildmode} to run the functions.
* Improve searching in an array. See https://stackoverflow.com/a/15394738.

$pkg_list_from_file and $bootstrap_pkg_list_from_file are arrays, they must be referenced as such. Fixes https://bugs.archlinux.org/task/71852.
Remove quotes from arithmetic expressions.

Add new -G option to set gpg's --sender. This allows to see who signed the rootfs image without needing to import the gpg key from the keyring in initramfs.
|
|
* Add --batch, since gpg is run in a script.
* Add --no-armor (this is the default). Armored output provides no benifit here.
* Add --no-include-key-block (this is the default). There is no need to have the gpg key in the signature. The mkinitcpio hook will verify the signature against the included keyring.
Remove the output files before running gpg. Otherwise gpg --batch will fail if they exist.

Fixes #147.

This could prevent a few issues when creating an image file when re-running mkarchiso after a failure.
Remove useless test before running rm -f. The command will always succeed.

mounting the file system
mkfs.ext4 with its -d option can "copy the contents of the given directory into the root directory of the filesystem".
This allows to get rid of the last directly used mount and umount commands in mkarchiso.
Additionally try to make the ext4 image somewhat reproducible by setting E2FSPROGS_FAKE_TIME to SOURCE_DATE_EPOCH, clearing the UUID and using a reproducible hash seed.
See https://git.kernel.org/pub/scm/fs/ext2/e2fsprogs.git/commit/?id=e1f7100643a46456be107b33098f6034b0835e6d .
Place mkfs.ext4 options in an array to avoid duplicating the command.

archiso/initcpio/*:
Remove mkinitcpio-archiso scripts as they have been split out into a separate project.
docs/README.{altbootmethods,bootparams}:
Remove mkinitcpio-archiso specific documentation.

archiso/mkarchiso:
Do not run `_build_iso_base` with `_run_once`, as it sets variables which are important to functions that are called
after it.
|
|
* Merge _make_efi_dir_on_iso9660 into _make_bootmode_uefi-x64.systemd-boot.eltorito since it's specific to that boot mode.
* Split off FAT image creation into _make_efibootimg, so it can be reused by other functions.
* Add/improve comments to better document what the script does.

This reverts commit 3d6651abf74ee4eb91212bd9a7d3478c95126cfb.
A missing $PATH breaks scripts that do not hardcode binary paths.

archiso/mkarchiso:
Generalize the handling of ucode files (e.g. copying, signing, size calculation) by introducing the global readonly
array of expected ucode names instead of hardcoding them in various functions.
When making use of ucode files in `_make_boot_on_iso9660()`, `_make_bootmode_uef-x86.systemd-boot.esp()` and
`_sign_netboot_artifacts()` create a list of files that is guaranteed to contain existing files.

Environment variables can interfere with the commands in chroot.
This causes issues when the environment variables specify a path that does not exist inside the chroot, e.g. if TMPDIR is set to a custom value.

archiso/mkarchiso:
Change `_make_pkglist()` to also generate the package list when using the netboot build mode.
|
|
archiso/mkarchiso:
Implement a buildmode to export artifacts required for netboot with IPXE.
When providing the buildmode 'netboot' via profiledef.sh or the `-m` option, all targets necessary to create an ISO
medium are built, but the components required for netboot are exported to the output dir.
Optionally, it is possible to provide a set of certificates for codsigning using the `-c` option, where the first file
is considered as the signer certificate and the second as the key.
Add `_export_netboot_artifacts()` to copy build artifacts to the output directory.
Add `_sign_netboot_artifacts()` to codesign the netboot artifacts in the work directory.
Add `_validate_requirements_buildmode_netboot()` to check for openssl.
Add `_build_iso_base()` to implement common function calls between the 'iso' and the 'netboot' buildmodes.
Add `_build_buildmode_netboot()` to make use of `_build_iso_base()`, (optionally) `_sign_netboot_artifacts()` and
`_export_netboot_artifacts()`.
Change `_build_buildmode_iso()` to make use of `_build_iso_base()`.
Add `-c` as an option to mkarchiso to read in a list of file names.
Unify the output of `_usage()` by using the same definition style for lists of strings provided to options that accept
them (e.g. `-c`, `-m`, `-p`).

archiso/mkarchiso:
Introduce a buildmodes array, that can be used to build towards more than one output artifact type.
Add a buildmode for building a bootstrap image (a compressed file containing a very minimal Arch installation).
The buildmodes can be set either using a `buildmodes` array in a `profiledef.sh` or by using the `-m` option flag to
mkarchiso and providing a space delimited, quoted list.
The 'iso' buildmode is always the default if no buildmodes are setup.
Implement building a bootstrap image, when using the 'bootstrap' `buildmode`, which uses a profile's
'bootstrap_packages.$arch' file to install packages using pacstrap and compressing it to a bootstrap image.
The name of the output file is currently constructed from the `iso_name` value by appending `-bootstrap`.
Replace the uses of `airootfs_dir` with the more generic `pacstrap_dir`, as the location denotes where pacstrap is
being used.
Replace uses of `img_name` with `image_name` and removing it from the global scope, so that it can be overridden per
each buildmode.
Rename `_cleanup_airootfs_dir()` to `_cleanup_pacstrap_dir()`.
Make `_run_once()` more generic by prepending the state files with a string defined by `run_once_mode`.
Add `_validate_requirements_buildmode_all()`, `_validate_requirements_buildmode_bootstrap()` and
`_validate_requirements_buildmode_iso()` to validate the general requirements of the different buildmodes.
Add `_build_bootstrap_image()` to generate the bootstrap image using bsdtar.
Rename `_build_iso()` to `_build_iso_image()` to fit the naming of the respective bootstrap function.
Extend `_read_profile()` to include the reading of bootstrap image specific packages from a file.
Extend `_validate_options()` to include testing of the bootstrap packages and running of validation functions for all
buildmodes.
Change `_set_overrides()` to override the buildmodes if they are specified via the `-m` option flag.
Change `_make_version()` to be used generically in all buildmodes.
Change `_make_pkglist()` to be used generically in all buildmodes.
Rename `_build_profile()` to `_build_buildmode_iso()` and set local variables that are specific to the buildmode, such
as `image_name`, `pacstrap_dir`, `run_once_mode` , `buildmode_packages` and `buildmode_pkg_list`.
Add `_build_buildmode_bootstrap()` and set local variables that are specific to the buildmode, such as `image_name`,
`pacstrap_dir`, `run_once_mode` , `buildmode_packages` and `buildmode_pkg_list`.
Add the `-m` option flag to the list of flags.
Closes #127

archiso/mkarchiso:
Change the help output to reflect that the `-g` option is generically signing a rootfs (which may be e.g. squashfs or
erofs).
Change the output of `_mksignature()` to be more generic, as it signs any type of understood rootfs image (which may be
e.g. squashfs or erofs).
|
|
archiso/mkarchiso:
Force the file extension in use for the PGP signatures of the rootfs to always be .sig.
When gnupg's 'armor' configuration option is used, the output otherwise defaults to using .asc.
As the verification hook in mkinitcpio-archiso expects the .sig file extension, verifying the rootfs will fail in that
scenario.

Use the gzip option -n/--no-name to prevent saving the original file name and timestamp.

$airootfs_dir before creating them with output redirection
mkarchiso creates "${airootfs_dir}/etc/machine-id" by using output redirection. If this file is an existing symlink, then the printf output would be written to the symlink target. It can be a big issue in case the symlink resolves to a path outside ${airootfs_dir}.
Fixes #121.

ISOs that will support BIOS booting
Some hardware, like Lenovo Thinkpad T420, will not BIOS boot if the disk has a valid GPT.
See https://bbs.archlinux.org/viewtopic.php?id=264096 .
Instead of a valid GPT, change to a valid MBR and invalid GPT similar to what was used before 729d16b48c99c5d9b23a89123ecde4ecacfa8705. That layout, despite having crazy partition tables, boots everywhere.
The difference is that -append_partition is still kept and specified before -isohybrid-gpt-basdat. Thus the appended partition will be listed as EFI system partition in MBR and as Microsoft basic partition in the invalid GPT.
Fixes #102.

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.

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.
