[ale] Interesting inode problem

CPIO's default archive format (bin) only supports the storage of 16 bit inode 
numbers.  The following archive formats (invoked with -H <format>) 
support 32 bit inode numbers:  crc, newc, ustar, or tar.  

Your first 30 or so items happen to use inode numbers less that 65,536, 
so they are archived without error.

One of my systems gave me a riddle for today.

I back up to tape (DDS2) using the following commands:

$ cd /
$ find ./ -print | /bin/cpio -oaBv | /bin/dd of=/dev/st0

What I found is that after about 30 items I got the following before every
file or directory is archived:

/bin/cpio: <name-of-item-archived>: truncating inode number

Is there something wrong here with my cpio command?  I've got plenty of room
on the tape.
