Code review comment for ~crass/casper:fix-toram

This bug should get fixed as it seems to affect all current Ubuntu based distributions. Currently when you boot an ISO file from the hard drive using the "toram" option, Ubuntu loads fine into RAM, but the problems start when you try to repartition and install Ubuntu from RAM to the hard drive.

Because the hard drive is left mounted after Ubuntu has loaded into RAM, you can't repartition the hard drive if you started the ISO file from the same hard drive partition.

There are a lot of cases when Ubuntu should be able to boot completely to RAM, allowing unmounting of the hard drive and let it repartition the hard drive, but this bug prevents that. This bug adds a lot complexity when users need to modify their initrds in Ubuntu installations manually.
