Fair enough.  I guess what I was saying is that the addition of the two
things I mentioned would make that part of cygcheck output all the more
valuable.  :-)

BTW, one thing that's been suggested a while ago is to have cygcheck
report the user mounts for "SYSTEM" -- that may prevent services from
working properly, and is rather hard to get from the command line (without
getting into the whole sysbash process, that is).
