Comment 3 for bug 1049223

Looking at the 22 bugs that I mentioned the vast majority have 'Command line' information in dmesg that references a cdrom for example:

bug-991520/Dmesg.txt:[ 0.000000] Command line: file=/cdrom/preseed/ubuntu.seed boot=casper initrd=/casper/initrd.lz quiet splash -- maybe-ubiquity

which leads me to believe they had chroot'ed into their Ubuntu system to repair a failed upgrade. There are also a few with 'rescue/enable=true' in the Command line, which is also likely a situation where people chroot'ed.

So I think the best thing to do is just block these package installation failures.
