Description Patrick Lauer gentoo-dev 2012-02-24 11:46:05 UTC 
Scenario: one cvs checkout shared between multiple chroots, long merge running in one, fixing stuff in the other, commit affects a to-be-merged package

Alternate scenario: emerge --sync while doing an update

The traceback is rather uninformative:

Traceback (most recent call last):

I guess we could handle this similarly to how EACCES is currently handled, and just bail out with a short error message showing the path of the missing ebuild.
