After creating an updateable core-image-base minimal Extensible SDK for a qemux86 target, "devtool sdk-update" fails as follows: $ source environment-setup-i586-poky-linux SDK environment now set up; additionally you may now run devtool to perform development tasks. Run devtool --help for further details. $ devtool sdk-update ERROR: Failed to update metadata as there have been changes made to it. Aborting. ERROR: Changed files: b' M poky/bitbake/lib/bb/pysh/pyshtables.py\n'
As a temporary workaround, eSDK user should create a global .gitignore and add pyshtables.py to it.
