I could live without it. It is required for RestrictFileSystems= in
systemd service units according to

easy fix?
I'm currently using ptxdist 2024.03.0 but is also reproducible on the
ptxdist master branch.

Put this in "platforms/kernel.fixup.in" in your BSP:
------------------------------->8----------------------------
## SECTION=base_kernel
config KERNEL
select HOST_SYSTEM_PYTHON3
------------------------------->8----------------------------
> I'm currently using ptxdist 2024.03.0 but is also reproducible on the

We should add that dependency Upstream as well. Something like
config KERNEL_PYTHON3
prompt "ensure Python3 is available"
bool
help
Python3 is needed at build-time when CONFIG_DEBUG_INFO_BTF is
enabled.

Thanks. I combined the two and added the following to
"platforms/kernel.fixup.in" in my BSP:
------------------------------->8----------------------------
## SECTION=base_kernel
config KERNEL
select HOST_SYSTEM_PYTHON3 if KERNEL_PYTHON3
config KERNEL_PYTHON3
prompt "ensure Python3 is available"
bool
select HOST_SYSTEM_PYTHON3
help
Python3 is needed at build-time when CONFIG_DEBUG_INFO is
enabled
------------------------------->8----------------------------
Then I enabled KERNEL_PYTHON3 in my platformconfig.
The kernel build gets further than before, but stops here:
------------------------------->8----------------------------

target: kernel.compile

Error 2
------------------------------->8----------------------------
I guess that is because of these lines in the upstream "rules/kernel.make":
------------------------------->8----------------------------
KERNEL_SHARED_OPT = \
$(KERNEL_MODULE_OPT) \
PAHOLE=false
------------------------------->8----------------------------
So it would probably require more work to upstream to support the
CONFIG_DEBUG_INFO_BTF kernel option in ptxdist.
Kind regards,
Ian

^^^^^^^^^^^^^^^^^^^^^^^^^^
I realize that line is redundant. It was left over from my experimentation!

And that should have been 'CONFIG_DEBUG_INFO_BTF' of course!
