I don't know who suggested system(3), but that sounds like the right
answer.  Any other solution is likely to stop working in some future
release, as the stuff used to parse /etc/fstab and other things change. 
A bug report complaining that a home grown mount command had stopped
working would meet little sympathy.

There is no plausible speed problem with system(3) applied to an NFS mount,
because the mounting overhead will dominate all else.

The automounter is probably a better alternative to meeting the need, as
opposed to implementing the currently chosen solution.
