| Yes it is: 
| 
| # mount | grep lv_root
| /dev/mapper/vg00-lv_root on / type ext4 (rw,relatime,user_xattr,acl,barrier=1,stripe=32,data=ordered)

Ok, so per my test suggestion, what does:

  find / \! -fstype ext4 -print -prune

show?

Is it useful to go:

  find / \! -type d -fstype ext4 -print -prune

What does "man find" say about the -fstype test? I haven't an F15 box to
hand to check against. Does that paragraph differ from the man on F13?

Cheers,

Surely it was of this place, now Cambridge but formerly known by the name of
Babylon, that the prophet spoke when he said, 'the wild beasts of the desert
shall dwell there, and their houses shall be full of doleful creatures, and
owls shall build there, and satyrs shall dance there.'
        - Thomas Gray (1716-1771)
