I am testing at work with a totally dpkged environment with chef doing the
maintenance. I turned off the chef stuff last week so that it wouldn’t
re-overwrite my 26.3 deb file. I’ll turn chef on, downgrade to 26.2, turn
off chef, test, install 26.3, test and report back. That should keep the
environment consistent between the two emacs versions.  I’ll also send
along a list of all the debs and the yums. Yeah we configure our vms as
redhat 7.3 or 4 or 5 ( I’ll look tomorrow) and then all the stuff we build
is in dpkg (because we have to support Solaris and aix too); I would prefer
not to identify my employer so please don’t ask. Or comment. :-)
