You can not write to /proc/mounts as it is read only 2. mount.nfs is broken (bug already filed) the way that it can not handle symlink /etc/mtab -> /proc/mounts properly. 3. I believe content handling of /proc/mounts is the kernel's job. If it does not do it well, it should be patched -> we should not patch automounter as it is not its responsibility. The similar with /etc/mtab - it is the mount responsibility to handle it.
