Package: cpio
Version: 2.6-18.1+etch1
Severity: important
cpio sometimes corrupts data copying files over 2GB. It seems to pad them with
null bytes. It prints an error, though it exits with success. Here is the
report I got from a user:
$ cpio --sparse -pdmv $a 2GB reliably!
Can you please log this as a bug with the maintainers of debian / cpio?
Good: 1.cwf (<2GB)
