Thanks for the information.
Is /etc/mtab a regular file on your system? It should be
a symlink nowadays:
$ ls -ldog /etc/mtab
lrwxrwxrwx 1 17 Feb 20 00:04 /etc/mtab -> /proc/self/mounts
Having mount to update mtab as a regular file is deprecated:
from Karel Zak's (the util-linux maintainer) blog:
"Yeah, mtab is evil."

as you pointed out that there is not a problem with df, I'm marking
this as "notabug" in coreutils' bug tracker.
Thanks & have a nice day,
