I'll be installing new kernels on all hosts this Thursday morning, expect a little bit of downtime and naturally, reboots of all machines. – tfheen

In order to fix a problem with BSD `mailx` and UTF-8 (yay legacy tools), I installed heirloom-mailx. Unfortunately, this also broke any commit hooks that used `-a` to set custom headers. Unfortunately, it doesn't look like Heirloom has a way to set arbitrary headers, so I have reverted this change. Sorry about the trouble, and you should have your commit emails back again. – tfheen
