Hi Martin,
Just an update: The patch you pointed out, includes following line:
+PACKAGECONFIG[python] =
"--with-python=${PYTHON},--without-python,,python3-core"
However, I found another patch from you:
https://patchwork.openembedded.org/patch/147883/
which includes:
+PACKAGECONFIG[python] =
"--with-python=${PYTHON},--without-python,python3-core,python3-core"
With that change, I was able to build core-image-minimal, and python3 is
removed from target rootfs.
Thanks for the help
Carlos

Hi Martin,
I've downloaded bind_9.10.6.bb recipe and applied the patch you pointed, but
do_install fails
error: invalid Python installation: unable to open

I've also tried the patch from Armin Kuster (Patch ID 151778), bind_9.12.1.bb
builds fine, but dhcp_4.3.6.bb do_compile fails

This error is similar to what is posted here:

Could you clarified if those errors were already handled, so I can fetch the
fix?
Thanks,
Carlos

I had the same issue a while back, and submitted this patch:
https://emea01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fpatchwork.openembedded.org%2Fpatch%2F148257%2F&data=02%7C01%7Ccarlos.bejar-colonia%40philips.com%7C5bf80069779142d49a9208d5db324507%7C1a407a2d76754d178692b3ac285306e4%7C0%7C0%7C636655931318995045&sdata=2QBW2XS2r7Kx3mQdTN%2BPVQpCvp%2Bh0TI7Ql6HPJymlBU%3D&reserved=0
Since then Armin incorporated my patch with his version upgrade here:
https://emea01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fpatchwork.openembedded.org%2Fpatch%2F151778%2F&data=02%7C01%7Ccarlos.bejar-colonia%40philips.com%7C5bf80069779142d49a9208d5db324507%7C1a407a2d76754d178692b3ac285306e4%7C0%7C0%7C636655931318995045&sdata=yIMyeknuFenkNPGtG7ItvX6WzNnhhNbF1Exoca9vmNw%3D&reserved=0
If you maintain your own meta layer, you can either create a bbappend file to
implement the package config feature, or you can simply add the updated version
from Armin.
