wic: Avoid problems with "-" characters in plugin names

2025-06-16T16:57:30+00:00

Remap "-" characters in plugin names to "_" so wic plugins can be extended using standard python class inheritance. This change means wic files can be incrementally updated over time to the correct name rather than breaking everything. Actual plugin module files will need to be renamed as done in previous patches. Also remove a double call to get_plugins() which isn't needed. (From OE-Core rev: 6d9c76196ffad39e628aff76d53d6ecbb517cfa1) Signed-off-by: Richard Purdie

wic: add WIC_SECTOR_SIZE variable

2024-10-29T11:19:57+00:00

Currently WIC is unable to generate images that requires a sector size different of 512. Add WIC_SECTOR_SIZE variable to handle the sector size of 4096 for UFS. For "wic ls" command modify get_partitions() to support WIC_SECTOR_SIZE.

wic: implement reproducible Disk GUID

2024-02-08T10:53:13+00:00

GPT based disks have a disk guid apart from the 32-bit disk identifier. This commit implements reproducible disk guid by using SOURCE_DATE_EPOCH (if available) value as a random seed (From OE-Core rev: 150e079589e207fe174d2dceb40cd8f3d3972c5a) Signed-off-by: Adithya Balakumar Signed-off-by: Alexandre Belloni Signed-off-by: Richard Purdie

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: Add argument --hidden to default imager

2023-05-25T09:29:08+00:00

Add argument --hidden to avoid MS Windows prompting to format partition after flashing to a USB stick, SD card on another media. Set Bit 0 (RequiredPartition) to mark that the partition is required for the platform to function on GUID Partition Table (GPT). The new argument simplifies setting RequiredPartition on GPT through a WKS file and the default imager plugin. Otherwise, without this feature, to achieve the same result a new imager plugin has to be implemented and set in WIC_CREATE_EXTRA_ARGS.

wic: use part_name when defined

2023-04-13T10:56:07+00:00

So far part.label has been used to define GPT partition label even if part.part_name was defined. Fix the code to use part.part_name whenever available, as it makes sense to have a GPT partition label which is different from the contained filesystem label.

wic: honor the SOURCE_DATE_EPOCH in case of updated fstab

2022-10-26T11:28:39+00:00

In case user requested to build a binary repeatable package, it's required to honor the SOURCE_DATE_EPOCH environment variable. So forcefully set mtime inside all the routines which modify fstab in case it is updated.

Revert "wic/plugins/images/direct: Allow changes in fstab on rootfs"

2022-09-28T07:01:11+00:00

Commit 20d43a2 allows changes in fstab for the / mount. However, if the fstab contains / already then this results in two entries for / in the fstab, which is confusing and results in systemd producing errors on boot: systemd-fstab-generator[11101]: Failed to create unit file /run/systemd/generator/-.mount, as it already exists. Duplicate entry in /etc/fstab? Wic should be extended to support merging mount points in fstab, but as we're about to release revert the patch that introduced this change as it hasn't been in a release yet, and the issue which prompted the patch in the first place can be revisited post-release.
