Description Richard W.M. Jones 2011-05-17 19:46:23 UTC 
Description of problem:

The 'file' command in Rawhide gives a strange output for a file
of all zeroes:

$ truncate -s 100M /tmp/test
$ file /tmp/test
/tmp/test: DOS-executable (

Or in case you think sparseness is a problem:

$ dd if=/dev/zero of=/tmp/test bs=1M count=100
100+0 records in
100+0 records out
104857600 bytes (105 MB) copied, 0.258742 s, 405 MB/s
$ file /tmp/test
/tmp/test: DOS-executable (

Version-Release number of selected component (if applicable):

file-5.07-1.fc16.x86_64

How reproducible:

100%

Note this is a regression over the previous version I was
using from Fedora 15, which printed "data".

Steps to Reproduce:
1. See above.
2.
3.
  
Actual results:

DOS-executable (

Expected results:

Something else, eg. the old "data" string.

Comment 2 Jan Kaluža 2011-05-18 11:14:46 UTC 
Thanks for submitting it upstream. It's regression in new version caused by new DOS device driver pattern, which is broken. I'm not sure how it was supposed to work anyway...
