This is a subsidiary to the 'more' discussion.  I partly tested a method
on Sys V R2, VAX 11/785.  One can fstat(2) to get the inode value and the
block-special identity.  One must find out the name of the device, perhaps
from stat'ting the disk devices until finding the right one (untested).
One then generates and runs a command "/etc/ncheck -i inode blockdevice".
On twitch one must be super-user to do that; I tried a file, and it took
several minutes for ncheck to find the name.  One then needs /etc/mount
to associate the device with the proper mount directory.  Whew!  Is there
a better way?  Someone suggested walking down from /.  How would he find
out the correct file system, assuming more than one file matched the inode
number?
