Quite right.  That is one of the reasons Linux is better than anything
else on the desktop.  Even if I haven't the foggiest idea what it's on
about (because of my own lack of knowledge) I greatly appreciate
detailed, informative error messages.  I could use a Mac and get `Error
No -237' and a little bomb graphic, or I could use Windows and get my
favourite `An error occurred'...

I assume it's the same thing on a superblock as on a file:  a
distinctive byte pattern that lets you recognize what type of file or
filesystem you're looking at.  man file and man magic for more
information...
