[Bug-cpio] What am I doing wrong?

[Alasdair Thomson]

What would cause cpio to stop working properly? I've always used it to 
copy directory trees from one place to another keeping the ownership and 
permissions intact, using:

find . -depth -print | cpio -pdmv /new/mnt/point

But now it's stopped working - regular files are owned by root and the 
permissions are not set. What could possibly cause this? For example, 
this is the original file system:

drwxr-xr-x  2 thomsona users     4096 2007-03-24 00:30 Office Documents
-rw-------  1 thomsona users     7846 2007-04-12 22:57 offsets.ods
-rw-r--r--  1 thomsona users     8705 2007-04-10 23:55 partitions.ods
drwxr-xr-x  2 thomsona users     4096 2007-03-20 19:36 pdf-files

And here is the copy:

drwxr-xr-x  2 thomsona users     4096 2007-03-24 00:30 Office Documents
-rw-------  1 root     root      7846 2007-04-14 10:25 offsets.ods
-rw-------  1 root     root      8705 2007-04-14 10:24 partitions.ods
drwxr-xr-x  2 thomsona users     4096 2007-03-20 19:36 pdf-files

Help! I've used cpio like this for the past 15 years without any 
problems on various Unix systems. Is this a bug or is there something I 
haven't done?

I'm using gnu cpio V2.7 on gentoo:

address@hidden ~ $ cpio --version
