If you have NFS mount points, you will see that it includes a great deal
of additional information about each mount.
OK, I see now:

This format is just awful for parsing. It's pretty clearly totally
ad-hoc. It's not even self-consistent (it uses different separators,
etc, in the same file!) It's reasonably compact for human consumption,
but it doesn't show what the arrays mean.
Heck, XML would have been better than this mess...
Sigh. So where where you when I asked for review time and again?
I have a couple of simple Python scripts that can parse this without any
difficulty.
I resent your tone. Quite a bit.
