Hi,
I am wondering if it is possible to hide the underlying filesystem
in a stackable filesystem configureation. 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.
Thanks
ttyl
Dima
