tmpfs not unmounted

[Sebastian]

Hi,

I have vmbuilder 453 running right now, since it has a working --tmpfs option. I looked at my running processes and the command to unmount the tmpfs was still running. I tried to unmount the tmpfs myself and it did not work. Nothing happend, the console was stuck after I typed "umount /path/to/tmpfs" in the shell. Also, trying to "kill" an unmount command did not work. Not with kill -9 and not with kill and not with killall.

I tried it on different machines, all of them with ubuntu lucid 10.04, and every machine showed the same behavior.
