This should duplicate everything (owner, group, perms)
if you run it as root, and /old and /new are local ext2 filesystems.
/new should exist and be EMPTY.
It may not set permissions on directories

Check your environment for any
settings that cpio uses.
# which cpio
/bin/cpio
# rpm -qf /bin/cpio
cpio-2.4.2-9
# rpm -V cpio
# which find
/usr/bin/find
# rpm -qf /usr/bin/find
findutils-4.1-25
# rpm -V findutils
