dal man di mount:
- --------
The auto type may be useful for user-mounted floppies.  Creating a 
file /etc/filesystems can be useful to change the probe order (e.g., to try  
vfat before  msdos  or  ext3  before  ext2) or if you use a kernel module 
autoloader.  Warning: the probing uses a heuristic (the presence of 
appropriate `magic'), and could recognize the wrong filesystem type, possibly 
with catastrophic consequences. If your data  is  valuable,  don't  ask  
mount  to guess.
[...]
  If no -t option is given, or
  if the auto type is specified, the superblock is probed for  the
  filesystem  type (adfs, bfs, cramfs, ext, ext2, ext3, hfs, hpfs,
  iso9660, jfs, minix, ntfs,  qnx4,  reiserfs,  romfs,  udf,  ufs,
  vxfs,  xfs,  xiafs  are  supported).  If this probe fails, mount
  will try to read the file /etc/filesystems, or, if that does not
  exist,  /proc/filesystems.   All  of the filesystem types listed
  there will be tried, except for those that are  labeled  "nodev"
  (e.g.,  devpts,  proc  and  nfs).  If /etc/filesystems ends in a
  line with a single * only,  mount  will  read  /proc/filesystems
  afterwards.
- --------


per farti una idea di come funziona, dai una occhiata a /proc/filesystems (da 
cui puoi ispirarti per fare il tuo /etc/filesystems personale)!

penso sia un comportamento normalissimo =)
