Chris and I did talk about this on irc:

(22:33:38) kergoth: actually fails even without prserv enabled at all
(22:34:07) kergoth: just import pydoc will call sysconfig.get_path() which enters that codepath
(22:34:22) kergoth: so calling anything that imports bb from a task will explode
(22:34:33) kergoth: cooker pulls in xmlrpc, which pulls in pydoc
(22:34:41) kergoth: breaks devtool modify
(22:37:04) RP: kergoth: right, it was more about it being a hint at the kinds of issues
(22:37:11) kergoth: ah, fair enough
(22:37:26) kergoth: i expect we may need to change how python3native is doing its thing
(22:42:55) RP: kergoth: quite possibly. I never liked that fix and suspected there was more to it :/
(23:21:39) kergoth: RP: maybe something like https://github.com/openembedded/openembedded-core/compare/master...kergoth:python-sysconfig ? i'll mull it over. makes sense, though. we rename _sysconfig only for the python3-native recipe, so it'd make sense for us to only change that name for our python, not any python run from the task
(23:21:49) kergoth: _sysconfigdata, that is
(23:46:35) RP: kergoth: something like that would make sense, yes

Chris: Did you come to any conclusion? 

Does someone want to send a patch?

Cheers,

Richard
