wic/engine: error on old host debugfs for standalone directory copy

2026-02-27T17:45:07+00:00

When wic is used in standalone mode, it relies on host tools such as debugfs. For directory host->image copies into ext* partitions, wic uses scripted debugfs "-f" input with multiple mkdir/write commands. Older host debugfs versions (< 1.46.5) may behave unreliably in this mode and can silently miss files. This does not affect builds using debugfs from OE where the version is known to be sufficiently new. Add a debugfs version check and emit an error when an older host debugfs is detected. The error is shown once per run and halts execution.

wic/engine: fix copying directories into wic image with ext* partition

2026-02-27T17:45:06+00:00

wic uses debugfs to write on ext* partitions, but debugfs can only write to the current working directory and it cannot copy complete directory trees. Running 'wic ls' on a copied directory show this: -l: Ext2 inode is not a directory Fix this by creating a command list for debugfs (-f parameter) when recursive parsing the host directory in order to create a similar directory structure (mkdir) and copy files (write) on each level into the destination directory from the wic's ext* partition.

wic: bootimg-efi: Support + symbol in filenames

2025-04-28T15:18:53+00:00

Allow the '+' symbol as a valid character in filenames listed in the IMAGE_EFI_BOOT_FILES variable. The '+' symbol might be used to support boot counting for boot entries, as described in the UAPI Boot Loader Specification [1]: The boot counting data is stored in the name of the boot loader entry. A boot loader entry file name may contain a plus (+) followed by a number. This may optionally be followed by a minus (-) followed by a second number. The dot (.) and file name suffix (conf or efi) must immediately follow. Boot counting is enabled for entries which match this pattern. Example: IMAGE_EFI_BOOT_FILES:append = " entry.conf;loader/entries/entry+3.conf" [1] https://uapi-group.org/specifications/specs/boot_loader_specification/#boot-counting (From OE-Core rev: 081fa0ebb33dbbfd0f6e8239690261c0a9dcdb2c) Signed-off-by: Igor Opaniuk Signed-off-by: Richard Purdie (cherry picked from commit 3f25822281eb9423ff86105eaebb0bed48663648) Signed-off-by: Jose Quaresma Signed-off-by: Steve Sakoman

wic: bootimg-efi: fix error handling

2024-08-01T13:08:09+00:00

If we check for empty variables, it does not make sense to print their content in case they are empty. Additionally, the error message in the 'kernel' check attempted to print the wrong variable ('target') which was not even defined, yet. Also, raising WicError doesn't require an extra newline.
