[Bug-cpio] --format=ustar and "file name too long"

[Lennart Enström]

Using GNU cpio version 2.5 rpm supplied with Fedora Core 2. Maybe some
kind soul is able to help me. 

Can not make cpio to handle long file names. In the man-pages it says
that --format=ustar should enable filenames as long as 256 chars but
even though none of my filenames (incl absolute path) are that long I
get the error message "file name too long" on several files.

This is how I create my archives:

find foodir -depth | cpio -o --format=ustar > archive

The reason I am using the ustar format is that cpio does not manage
large files as discussed in previous postings so I decided to try with
another format.

Am I doing something wrong here? Thx /Lennart
