[bitbake-devel] [PATCH v3 05/15] knotty.py: Add the ability to spawn screen directly from knotty with OE_TERMINAL=screen_inline

[Jason Wessel]

The oe-core has a change pending to add the screen_inline class.

This change allows the simple use case of directly using a devshell
from the controlling terminal that started bitbake which is a
significant convience for some use cases.
