wic: use E2FSPROGS_FAKE_TIME and hash_seed to generate reproducible ext4 images

2023-12-21T10:38:30+00:00

E2FSPROGS_FAKE_TIME: sets fixed times for the inodes in the file system. hash_seed: creates reproducible directory indexes in the file system.

wic: extend empty plugin with options to write zeros to partiton

2023-12-06T22:55:49+00:00

Adds features to explicitly write zeros to the start of the partition. This is useful to overwrite old content like filesystem signatures which may be re-recognized otherwise. The new features can be enabled with '--soucreparams="[fill|size=[S|s|K|k|M|G]][,][bs=[S|s|K|k|M|G]]"' Conflicting or missing options throw errors. The features are: - fill Fill the entire partition with zeros. Requires '--fixed-size' option to be set. - size=[S|s|K|k|M|G] Set the first N bytes of the partition to zero. Default unit is 'K'. - bs=[S|s|K|k|M|G] Write at most N bytes at a time during source file creation. Defaults to '1M'. Default unit is 'K'.

wic: bootimg-efi: Make kernel image installation configurable

2023-12-04T11:23:37+00:00

The issue with installing the kernel image to both rootfs and boot partition is that some systems rely on the kernel image in rootfs and not in the boot partition. This leads to duplication of the kernel image, which can cause unnecessary storage usage. This patch provides a solution to the problem by adding a new parameter "install-kernel-into-boot-dir" to the wic kickstart file. If this parameter is set to 'true', the plugin will install the kernel image to the boot partition. If the parameter is set to 'false', the plugin will skip installing the kernel image, avoiding duplication.

wic: rawcopy: add support for zstd decompression

2023-11-27T22:54:59+00:00

Add support for zstd decompression in rawcopy plugin. zstd claims to reach higher, uniform decompression rates. (From OE-Core rev: 707471b71a417187f1e581d0c540e058825f7242) Signed-off-by: Malte Schmidt Signed-off-by: Lukas Funke Signed-off-by: Richard Purdie

wic: Add console parameters to qemux86 canned-wks

2023-10-04T22:05:54+00:00

Currently our wic test images boot up without kernel output on the consoles which means we have no way to debug if anything goes wrong. Add the console parameters runqemu would have added if the kernel wasn't built into an image to improve our chances of debugging.

wic: Add gpt-hybrid partition layout

2023-09-02T10:47:50+00:00

Add support for formatting a disk with a hybrid MBR & GPT partition scheme. In this scheme, the primary partitioning method is GPT, but a valid MBR header is also written than can point to a subset of the GPT partitions on the disk (any partitions marked with the `--mbr` flag will be included in this MBR). The primary purpose of this method is to allow for SoCs that can only find a bootloader in an MBR partition to use GPT once the bootloader is running. As an example, older versions of the Raspberry Pi firmware can only parse MBR partitions to find a kernel (or other bootloader like u-boot), but once those have booted GPT partitions can be used. In addition to the partitions annotated with the `--mbr`, a "protective" GPT partition of type 0xEE is added, as the existence of such a partition is the indication to tooling that this a hybrid MBR and that the GPT partition table should be parsed instead.

wic: fix wrong attempt to create file system in upartitioned regions

2023-08-21T10:34:12+00:00

The kickstart parser defaults fstype to "vfat". This leads to an attempt to create an empty file system even for regions configured with "--no-table" if used without fstype when no --sourceparams given. The fix tests for fstype "none" or no_table in Partition prepare method. This will omit the file system creation an the potential error for small region with --no-table option.

wic: bootimg-efi: Stop hardcoding VMA offsets

2023-08-09T20:43:33+00:00

Section VMA's are currently hardcoded. This doesn't work anymore starting with systemd-boot v254. Follow the actually solution to this which is documented here: https://wiki.archlinux.org/title/Unified_kernel_image#Manually This is also used by dracut. Later on, we may want to switch to ukify instead but this is not ready yet. (From OE-Core rev: 3abf99a6c6bde2fb8770f54dba609b35f6c6ee5a) Signed-off-by: Alexandre Belloni Signed-off-by: Richard Purdie
