[Bug 493020] [NEW] vmbuilder: Deletes most of /dev on interrupt

[Eric Hammond]

Public bug reported:

I'm running vmbuilder on the latest EC2 Karmic AMI.  When I Ctrl-C
interrupt the run, it deletes almost all of the devices in /dev making
the system somewhat unusable.

Here's a log demonstrating this.  I have reproduced the problem on a
fresh AMI by interrupting it in about the same place.  Before vmbuilder
was run, there were the usual hundreds of entries in /dev

I verified that /dev was full right before I pushed Ctrl-C and that it
was cleared out right after vmbuilder exited on the interrupt.

Let me know if you are unable to reproduce this problem or need further
information.
