looking at 'unlink (2)'
I see,
        if (vp->v_type != VDIR ||
            (error = suser(p->p_ucred, &p->p_acflag)) == 0) {
                /*
                 * The root of a mounted filesystem cannot be deleted.
                 */
                if (vp->v_flag & VROOT)
                        error = EBUSY;
                else
                        (void) vnode_pager_uncache(vp);
        }

I translate this as:
"if it's not a DIR, or we are root",
check if we are deleteing the 
root of an FS,
if not, flush cache......

now, if we were NOT root, and it IS a dir...... (normal...)

can we delete it?
I'm about to try this..
if you dont hear from me, the building exploded...
