Several weeks ago I started transitioning some Ubuntu VM’s to FreeBSD VM’s . On previous VM’s I was able to use the following command line without any problems

sudo phing code-update

After switching to FreeBSD I found that sudo, or its “sudo -E” variant, was having problems when running in sub shells. Phing svn tasks were asking for passwords that were previously setup to use svn+ssh. Using “sudo svn list svn+ssh://svn.example.com/svn/project” worked but not when phing ran. It turns out there are two environment variables that Ubuntu’s sudo package was preserving: HOME & MAIL. NOTE: Ubuntu 14.04LTS’ sudo package appears to only preserve HOME.

I created /usr/local/etc/sudoers.d/svnusers

Defaults env_reset
Defaults env_keep+="HOME"

This made FreeBSD’s sudo work as it had on Ubuntu. A day’s worth of investigation to solve the riddle but it works as I would expect it to.
