Take CD-RW, insert it. gnome-volume-manager mounts it. /proc/sys/dev/cdrom/lock = 1. Pressing the CD-ROM button does not eject. Burn the CD-RW (you can do this due to bug 132756). /proc/sys/dev/cdrom/lock = 1, still. However, pressing the button now *does* eject the CD. (Doesn't unmount it, though. Yay for 'VFS: busy inodes on changed media'.
Davej's plan for world domination. 1. bug gets filed, overlooked, and lost among the zillions of others.. 2. wait 12 months and ask if its reproducable. 3. profit ?
Don't think it happens now. Probably a sideeffect of the burning-while-mounted.
