The change is r25463 (http://diswww.mit.edu/menelaus.mit.edu/source-commits/26223), which should be minimal because:
- All it does is whine at you on stderr if you're using LPRng syntax
- It only affects printing invoked via command-line LPRng
It's quite conceivable that some program somewhere tries to call out to 'lpr' and explodes if it sees anything on stderr. But this will not affect any GTK+ printing, or anything that goes directly through the CUPS subsystem, unless users deliberately try to use "Print to LPR". Unaffected programs should include: Firefox, Evince, LibreOffice. Probably unaffected programs include MATLAB and Acrobat.
The backout strategy is revert the commit, rebuild, deploy. Since this is a change to a single package, and not a dependency, and doesn't involve the updater, we should be able to recover within 6 hours of catastrophe.
