Comment(by Quozl):

 Why do I think ext4 is being used?  I am in error.  I trusted certain

 The output of /bin/mount shows it is.  This turns out to come from
 /etc/fstab which says ext4.

 On a unit running os34, output of /proc/mounts says mmcblk0p2 is ext3, yet
 output of /bin/mount says mmcblk0p2 is ext4.  /etc/fstab also says ext4.
 "file -s /dev/mmcblk0p2" says ext3.
