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.

wic: implement binary repeatable disk identifiers

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

When SOURCE_DATE_EPOCH variable is set, binary repeatable build is expected. This commit implements reproducable disk identifiers in such a case using its value as a Random seed.

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.

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

2022-05-27T22:50:48+00:00

Allow wic to also manipulate the rootfs entry in fstab, which it currently refuses to write. Reasons one might want to do that include using systemd-growfs via --fsoptions on / With this change / is now handled exactly the same as other mountpoints, the former exception seemingly was not even documented.

wic: added fspassno parameter to partition

2022-05-16T22:19:18+00:00

The `fspassno` parameter allows to overwrite the value of the last column (`fs_passno`) in the /etc/fstab of the target root file system. This allows to have periodic file system checks.

wic: do not use PARTLABEL for msdos partition tables

2022-04-22T22:42:51+00:00

When using "msdos" partition tables and "--label" but not "--use-uuid" one can generate images which will not find their root, because PARTLABEL does not work for "msdos". Fix that by simply not going the PARTLABEL path in case of "msdos".
