I searched the source for cloud-init in Rawhide, and it doesn't
mention PATH at all, except in one example.  So I conclude that
cloud-init doesn't set PATH at all and must get it from systemd.
(I can't find out what environment systemd sets up by default either ...
Ask Lennart?)

IMHO there's probably a case for filing a bug with upstream cloud-init
and getting them to drop something like:

  Environment=PATH=[some predictable path]

into cloud-init-0.7.2/systemd/cloud-*.service.
