Hi,
After image build completes, rootfs directory is wiped by rm_work_rootfs.
If the image recipe is built again without clean, for example when
TESTIMAGE_AUTO is enabled to run tests, then rootfs task will not
run and thus wic uses an empty rootfs directory to populate the rootfs which
of course then fails at runtime.
How to fix this?
I know RP doesn't like rm_work, but I really need it. I can't leave all
builds laying around and bitbake IPC setup fails if a lot of IO is wiping
build/tpm's while recipe parsing is happening (the famous 30 second timeout).
wic image related tasks could possible depend on do_rootfs instead of
do_image_complete but seems to break the whole do_image_complete design.
Should rm_work_rootfs be moved from after do_image_complete to after
do_image_wic
if wic images are used?
Or should users just remember to "bitbake -c clean image && bitbake image" if
things
fail?
There are some other issues with testimage.bbclass and leaking cooker processes
which confused me for a long time but I'll try to send patches for those.
Does changing:
image_types_wic.bbclass:
bb.build.addtask('do_image_wic', 'do_image_complete', None, d)
to
bb.build.addtask('do_image_wic', 'do_image_complete', 'do_rootfs', d)
help?
This did not help. I need to dig deeper. Some of my changes may be
triggering this. I'm seeing this now on aarch64 and x86_64 build machines.
Cheers,

Hi Mikko,
my two cents: do you have the rm_work enabled? I've seen something
similar in the past, but with initramfs (the generated cpio.gz file
sometimes was empty). It seemed that adding and then removing a change
to the image triggered the problem, as if an older but "corrupted"
sstate has been used.
I've not found the time to dig into that, but I supposed that rm_work
could be the culprit.
Hope it could help and not add more confusion.
Cheers
