This means that if it displays a CD-ROM or a automount directory it cannot be umounted, which would be annoying.
Hmm, a O_WEAK flag needed? This could be hard to fit into the existing reference-count based VFS though.
Another alternative would a layer like supermount that allows umount with active descriptors, but this would be a rather radical change from the sysadmin level (more radical than the IRIX solution, which uses a daemon and some kernel hack)
