Description of problem:
When copying files to the floppy disk, the file permissions are
getting modified. The modification is that the file permissions are
increased in capabilities. read/write files are turned into executable
files. For example:

[root@linux fd_test]# touch test.txt
[root@linux fd_test]# ls -l test.txt
-rw-r--r--    1 root     root            0 Feb 11 10:18 test.txt
[root@linux fd_test]# mount /dev/fd0
[root@linux fd_test]# cp test.txt /mnt/floppy/
[root@linux fd_test]# ls -l /mnt/floppy/
total 0
-rwxr-xr-x    1 root     root            0 Feb 11 10:18 test.txt
[root@linux fd_test]# cat /etc/fstab | grep floppy
/dev/fd0         /mnt/floppy             auto    noauto,owner    0 0
[root@linux fd_test]# umask
0022
[root@linux fd_test]# umask 077
[root@linux fd_test]# touch test2.txt
[root@linux fd_test]# ls -l test2.txt
-rw-------    1 root     root            0 Feb 11 10:20 test2.txt
[root@linux fd_test]# cp test2.txt /mnt/floppy/
[root@linux fd_test]# ls -l /mnt/floppy/test2.txt
-rwxr-xr-x    1 root     root            0 Feb 11 10:20
/mnt/floppy/test2.txt
[root@linux fd_test]#

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