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 </tmp/a
cpio: Read error at byte 0 in file
R_2008_11_20_23_55_47_FLX02080314_adminrig_10831/D_2008_11_21_08_37_25_sge055_fullProcessing/regions/2.cwf,
padding with zeros

I performed an strace on the two files (1.9G, 2.1G) (neither are sparse) 1.cwf
and 2.cwf. 1.cwf works just fine but 2.cwf always breaks. Then I made a
different 2.1G file and that broke, so the problem looks to be that cpio cannot
copy files >2GB reliably!
Can you please log this as a bug with the maintainers of debian / cpio?
Good: 1.cwf (<2GB)
