Hi Pratik,

Thanks for the patch.

Do you have any clue about why this is triggering some selftest
failures? I'm a bit surprised by that, but I confirm it comes from this
patch:

I also note some is install error:

ERROR: lib64-core-image-sato-sdk-1.0-r0 do_rootfs: Could not invoke dnf. Command '...' returned 1:
...
Error: Transaction test error:
  file /usr/bin/g++ conflicts between attempted installs of lib64-g++-symlinks-15.2.0-r0.x86_64 and g++-symlinks-15.2.0-r0.core2_32

Finally, I note a ptest failures (on riscv64). This one look like
intermittent, if it happens too often, we might want to exclude the
failing test:

Failed ptests:
{'libffi': ['libffi.complex/complex_int']}

https://autobuilder.yoctoproject.org/valkyrie/#/builders/56/builds/1576


I will try to run more tests, as again, I'm a bit surprised by some of
these failures.

Thanks,
Mathieu
