Have you ever tried to simply umount() it with MNT_FORCE set? (The equivalent of ``umount -f''.) I assume it's only busy since there are device nodes on the fixit floppy that are currently in use by the kernel, even though they have not been opened using the pathnames from the fixit /dev. I've noticed earlier that the kernel gets confused in this situation. umount(..., MNT_FORCE) works around this. Another plea for DEVFS... -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
