unmounting all nfs filesystems without unmounting local ones

Hi there --

I want to unmount all NFS filesystems on one of our systems, while retaining the local mounts. The umount -a command comes to mind, but
when I run it, the /boot filesystem also gets unmounted, and I need
that one to remain available.

What would the correct command syntax to use in this case. The operating
system in question is the Fedora Core 2 distribution. Thanks.

why not
# umount -a -t nfs
this will umount all file systems which are nfs

<from man page>
-t vfstype
