The following series updates the wic to the latest one from
openembedded core. The git tree is available here.
https://github.com/vj-kumar/isar/tree/wic/staging0
Below are summary of key changes in the below series.
P3 & P6:
The latest version of WIC detects the presence of fakeroot using
pseudo_dir(${IMAGE_ROOTFS}/../pseudo). If this is non-existent it doesnot
use fakeroot. P3 handles that quirk. There is also a standalone invocation of
pseudo which P6 tries to handle via wic_fakeroot.
In case of ISAR, we need wic_fakeroot as fakeroot only for 2 purposes.
1. To workaround fsck return values for stretch
2. To handle standalone invocation of pseudo(P4 in series)
Number 2 is not needed if we dont use fakeroot.
The alternative approach to fakeroot is to carry patches on top of wic
directory instead of working around such quirks using fakeroot. The downside
being the need to rebase the local changes on future updates of wic.
P4 & P5:
These cherry-picked changes address the --exclude-path issues which Henning
has addressed in [2]. Should be dropped once that is merged.
P9:
P9 is needed for --include-path to work. I have observed that --include-path
does not yet work/broken in the latest OE-core/poky. Posted a query in [1]. In ISAR
it works with P9 fix. P9 fix could also be relevant upstream and can be sent there
for review.
Apart from the normal qemu build test, Below are the list of features tested.
KS API:
--exclude-path
--include-path
--fsuuid
--overhead-factor
--fixed-size
--use-label
--use-uuid
Standalone invocations:
wic ls
wic cp
wic rm
Currently in the process of finding a way to test wic features automatically. Some wic features
like -fsuuid cannot be validated till we boot the target. Need to find a generalized way for
testing the available wic features. The approach in hand is to use a wic-test.wks file and
generate qemu image with that to validate the wic features.

+ Create MBR + EFI boot partition
+
+ This plugin creates a boot partition that contains both
+ legacy BIOS and EFI content. It will be able to boot from both.
+ This is useful when managing PC fleet with some older machines
+ without EFI support.
+
+ Note it is possible to create an image that can boot from both
+ legacy BIOS and EFI by defining two partitions : one with arg
+ --source bootimg-efi and another one with --source bootimg-pcbios.
+ However, this method has the obvious downside that it requires TWO
+ partitions to be created on the storage device.
+ Both partitions will also be marked as "bootable" which does not work on
+ most BIOS, has BIOS often uses the "bootable" flag to determine
+ what to boot. If you have such a BIOS, you need to manually remove the
+ "bootable" flag from the EFI partition for the drive to be bootable.
+ Having two partitions also seems to confuse wic : the content of
+ the first partition will be duplicated into the second, even though it
+ will not be used at all.
+
+ Also, unlike "isoimage-isohybrid" that also does BIOS and EFI, this plugin
+ allows you to have more than only a single rootfs partitions and does
+ not turn the rootfs into an initramfs RAM image.
+
+ This plugin is made to put everything into a single /boot partition so it
+ does not have the limitations listed above.
+
+ The plugin is made so it does tries not to reimplement what's already
+ been done in other plugins; as such it imports "bootimg-pcbios"
+ and "bootimg-efi".
+ Plugin "bootimg-pcbios" is used to generate legacy BIOS boot.
+ Plugin "bootimg-efi" is used to generate the UEFI boot. Note that it
+ requires a --sourceparams argument to know which loader to use; refer
+ to "bootimg-efi" code/documentation for the list of loader.
+
+ Imports are handled with "SourceFileLoader" from importlib as it is
+ otherwise very difficult to import module that has hyphen "-" in their
+ filename.
+ The SourcePlugin() methods used in the plugins (do_install_disk,
+ do_configure_partition, do_prepare_partition) are then called on both,
+ beginning by "bootimg-efi".
+
+ Plugin options, such as "--sourceparams" can still be passed to a
+ plugin, as long they does not cause issue in the other plugin.
+
+ Example wic configuration:
+ part /boot --source bootimg-biosplusefi --sourceparams="loader=grub-efi"\\
+ --ondisk sda --label os_boot --active --align 1024 --use-uuid

In the latest wic, wic.utils is removed and part of the implmentation
is moved to wic.misc. Fix the wic imports accordingly.

The latest WIC doesnot use fakeroot if pseudo_dir(IMAGE_ROOTFS/../pseudo)
is non-existent. This results in wic_fakeroot not being used. Create a
dummy pseudo_dir to satisfy wic.
WIC hardcodes the python(/usr/bin/python3-native/python3) to be used
while running bmaptool. The above path is OE specific and hence breaks
build in ISAR. Create a symbolic link in the above location to satisfy
wic.

This function creates hard links if possible, falling back to copying
the file if the destination is on a different volume to the source.
The docstring for copyhardlinktree() is also updated to make the

The comparison of the stat st_dev is not enough to judge whether
hardlinking will work. One example would be where you try and hardlink
across two bind-mounts of a directory. The st_dev will be the same and
the operation will still fail.
Instead of implementing a check to try and figure out hardlink support
just try hardlinking and fall back to a copy when running into an
exception.

When using --exclude-path option wic copies the rootfs to a new location
and invokes pseudo as a standalone command to rebuild the database in the
new rootfs.
This is not applicable when using wic_fakeroot. Return 0 for such
standalone invocations in wic_fakeroot.
It also looks for files.db inside the pseudo directory and throws an
exception if it is not found. Handle that too.

exec_native_cmd doesnot search for the binaries in /bin.
Commands like tar which are essential for certain wic operations
are present in /bin in distros like debian.

In the older version of wic, the fstab entry for /boot mountpoint
was skipped.
However in the latest wic this is not the case. Adding a /boot
mountpoint in part results in creating a fstab entry for automount.
Remove it to avoid the unwanted mount which overwrites the contents
of /boot in debian rootfilesystem.

FWIW, I've tested a couple of images built by jailhouse-images, and no

Thank you Jan. Also, I have tested the wic with jailhouse-images &

P9 fix is sent to OE-core mailing list. Currently in master-next. Hopefully
should get merged.
https://lists.openembedded.org/g/openembedded-core/message/142048
I will send a V2 with updated P9 commit.
I would cherry-pick and carry P9 version from OE-core once it is merged to
master. We could drop that
the next time we update wic.
FWIW, --include-path is fixed in OE-core with the below patch. It is merged
to master.
