[M3devel] cm3 is broken

[Jay]

Upgrade is failing because cm3 is already broken. I can see about making the error clearer.


 I often upgrade.py nocleangcc to speed it up.


Right, backup must include libm3 m3core cm3cg cm3 config. See capture-min or capture-boot, I think I settled on capture-min.


m3cc either needs to keep the "front" tag or the scripts need to mention it explicitly. You can't safely always skip it.


Do you have recourse?
Old release maybe? (Be sure to edit the 5.8.6 config to avoid new cm3cg.)
