does unionfs work? I just tried mounting a CD and union mounting another filesystem on top of it, following the directions in the man page for mount_union. I mounted /dev/cd0a on /usr/src and then did mount -t union /usr/obj /usr/src and now df reports: /dev/sd1a 34111 12282 19100 39% / /dev/sd1s2f 306321 134405 147410 48% /home /dev/sd1s2e 297423 108517 165112 40% /usr /dev/sd0s4e 304618 227217 62170 79% /usr/local /dev/sd0s4a 15034 1851 12431 13% /mnt procfs 4 4 0 100% /proc /dev/cd0a 613384 613384 0 100% /usr/src <above>/usr/obj 910807 721901 165112 81% /usr/src and there is nothing showing in /usr/src, nor can I figure out how to umount it either. because if I change directories to /usr/src it says I'm in /usr/obj and umount /usr/src says /usr/obj isn't mounted. -josh
