Incredible!  An honest to goodness manpage for blkid?  By golly, so it does, 
Amazing...  I have gotten used to all this new stuff not having one cuz the 
authors are too busy|lazy to write a manpage for their latest masterpiece. :(  

The audio guys in particular.  Sometimes I long for the OSS days, at least it 
worked when it worked, not this heavily distorted from overloads whisper at 
subliminal levels for all system sounds I have now.  From FF, all the plugins 
work great, but kde's sound effects other than the Charge that k3b plays at 
the end are of the did I hear that, or was that my imagination working 
overtime.  There is no one on this list who has the foggiest idea how to get 
the crap fedora ships to actually work, and only maybe 10% of it has manpages.

So I first gave it the argument /dev/sdc, figuring it would just show that 
device, but that returned a null.  By itself with no argument, the whole list 
in short form.  Nice.  fstab fixed.  Thank you.
