My only suggestion would be to define the value of
the security context using a variable, so it's
easier to see that the thing you're editing out of
/etc/mtab is identical to the thing that was
supplied as a mount option.  I.e., define
    MOUNT_CONTEXT="system_u:object_r:nfs_t:s0"
and use it in the two spots elsewhere.

But even if you don't take that suggestion this
looks good to me.
