Thanks.  Sounds like it would be useful to document this variable.

I can't seem to find any information on this variable other than what was offered in a bug (https://bugzilla.yoctoproject.org/show_bug.cgi?id=3662) filed against some stuff in the glossary in general.  The information provided there by Robert P. J. Day says it is handy when layers get out of sync.

Can anyone out there offer more information on this variable?  Wondering whether this should be documented in the glossary.

Normally, if bitbake encounters a bbappend whose recipe no longer exists, it treats this condition as fatal. This, as Robert says, often occurs if layers get out of sync. For example, if oe-core bumps a recipe version and the old one no longer exists, but the other layer hasn't updated to the new version yet. It being fatal is a sane default, as it's important to realize when your changes are no longer being applied. The variable you mention changes the behavior to a warning instead.
