Well, in src/pk-main.c we do clearenv - we don't need to - but it
prevents packagekitd being run differently when being run system
activated and when being run manually.

In src/pk-spawn.c we do a g_spawn_async_with_pipes with no environment,
which Ken is correct is for security. This is the sort of security from
the "I don't know what is unsafe, so pass nothing" school, and can
certainly be improved by someone who knows better than me.

It would certainly be valid to preserve PATH, but the question is why
you would want to. Why goes wget rely on PATH?
