In the docs on http://www.gentoo.org/doc/en/handbook/handbook-x86.xml?part=2&chap=5 it states "The env-update script will append the values in the alphabetical order of the /etc/env.d files. This is why many of the files in /etc/env.d begin with a number." Instead it should be made clear that the files must begin with a number, otherwise evn-update will ignore it. Reproducible: Always Steps to Reproduce: 1. 2. 3.
Fixed. Thanks for reporting.
