The hard part about this is that lintian has no way of knowing which files
are in /bin and /sbin. I suppose we could maintain a static list, but
that looks extremely unattractive. I'm not sure that lintian is the right
tool to use here.
This looks to me like a hard problem, particularly given that checking
this means knowing whether programs invoked without a path are actually
shell built-ins (and since such an init script may be a /bin/bash script,
there are lots of those).
