Hello,
coreutils 8.20 df output is correct, showing all mounted filesystems:

But starting from coreutils-8.21 (i.e. the bug exist in 8.22 and 8.23
too), lots of NFS mounts are missing:
address@hidden:/var/tmp/vmk$ coreutils-8.21/src/df

machine-2:/var/spool/mail 230608384 83144160 135929888 38% /var/spool/mail
The contents /etc/mtab are correct and "mount" command also works
correctly. Could you look into this issue please?

EL7 would get that backport independently of a new release.
That's now tracked at https://bugzilla.redhat.com/1197463
