wic/partition.py: Set hash_seed for empty ext partition

2024-06-18T07:44:41+00:00

Although setting hash_seed is handled for the rootfs plugin case, but this is missed when deploying an empty ext partition. (From OE-Core rev: 0202fb594fb05098cb8d8b6088e63beb40b5906e) Signed-off-by: Adithya Balakumar Signed-off-by: Richard Purdie

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: 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: 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: Fix usage of fstype=none in wic

2023-02-15T10:21:34+00:00

This allows to specify partition with fstype=none in the wks file to have partition created but without following mkfs. The none fstype is in the list already but the usage is not documented. Example; part /data --ondisk mmcblk0 --fstype=none --align 4096 --fixed-size 512 will create a partition, filesystem may be created manualy on the host or target and data will be preserved if the device is reflashed using same wks. Works with bmaptool and probably does not work with dd. Use case is persistent filesystem/data between reflashing of the image.

wic: make ext2/3/4 images reproducible

2022-11-07T21:57:21+00:00

Ext2/3/4 FS contains not only mtime, but also ctime, atime and crtime. Currently, all the files are being added into the rootfs image using mkfs -d functionality which affects all the timestamps excluding mtime. This patch ensures these timestamps inside the FS image equal to the SOURCE_DATE_EPOCH if it is set.

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: 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.
