Description Bastien Nocera 2006-05-19 10:43:28 EDT

Patch from Keiichi Mori <kmori@redhat.com>

After a default installation, this line from the /etc/fstab:
LABEL=/                 /                       ext3    defaults        1 2
gets removed by fstab-sync.

The while loop to parse the options is:
   978 static boolean
  979 fs_table_line_has_mount_option (FSTableLine *line, const char *option)
  980 {
  986   p = line->mount_options;
  987   q = p;
  988   while (*q != '\0')
  989     {
  990       while (*q != ',' && *q != '\0')
  991         q++;
  993       if (strncmp (option, p, q - p) == 0)
  994         return TRUE;
  996       q++;
  997       p = q;
  998     }

When the end of the options is reached, p == q, so the strncmp retval will be 0,
as an strncmp of 0 length is always 0.
