Where can we find more details re the best ways of removing GPLv3 components
please?
Or, starting with a clean slate and adding back only what we actually need (for
i.MX 8X and Qt Commercial).
Have tried searching, but going round in circles, as all the results so far
still point back to meta-gplv2.
Including the "How do I":
"If you use INCOMPATIBLE_LICENSE to exclude GPLv3 or set PREFERRED_VERSION to
substitute a GPLv2 version of a GPLv3 recipe, then you must add the meta-gplv2 layer to
your configuration."

The context is that some of our customers require Secure Boot and Chain of
Trust (in an embedded environment).
If we keep GPLv3 components, then we need to provide "any methods, procedures,
authorization keys, or other information required to install and execute modified
versions of a covered work".
The suggested way nowadays is to set INCOMPATIBLE_LICENSE only for the
image that is actually going to ship in a product, then work your way
throgh specific gpl3 dependencies that get pulled in, and eliminate
them one by one - precisely how is impossible to tell beforehands, but
typical problems are bash scripts (which you need to package
separately and not include into the product, or rewrite in posix shell
and use #!/bin/sh), or optional dependencies on things like readline,
which can be switched off via PACKAGECONFIG tweaks.
Thanks for raising this question, and thanks to Alex for providing
guidelines.
I agree that the current wiki and documentation don't provide enough
information on excluding GPLv3 packages. I'll propose an update to the
manuals. Stay tuned on the docs mailing lists...
Cheers
Michael.
