dump is a command that uses those fields.  We do build dump in LFS or 
BLFS, but someone might want to use that.


dump is really obsolete.  The better command is rsync.

In any case, the traditional interpretation is that file systems that 
need to be saved/backed up (i.e. dumped) are 1, and pseudo file systems 
are 0.  I see no reason to change that.

That's was the man page says, but RedHat uses 'swap'.  Ubuntu uses 
'none'.  In practice, the mount point is ignored if the type is swap. 
It doesn't make any practical difference.

I can go either way.
