How are you spawning your child processes? Is it simple enough to wrap all calls that create child processes so that those call sites iterate through environ and shove it back into the OS level environment, so that the child inherits the right thing, while not worrying about the OS level environment for the rest of the process? -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
