For example. In the nullfs example you would do the following to mount it: mount /dev/adXsYZ mntpoint (UFS fs) mount -t nullfs mntpoint nullfs_mntpoint (NULL fs) Now both mntpoint and nullfs_mntpoint is visible to the user. Ideally what I would like to do is have the user enter mount -t nullfs /dev/adXsYZ nullfs_mntpoint (UFS fs) and have them see only the nullfs mntpoint rather than both mntpoint and nullfs_mntpoint. Is this possible??? I would still like the underlying FS to be UFS.
