You would need to copy that snapshot to a whole new partition to have a full filesystem with integrity and then mount that partition possibly in a fake root (????) - not sure how to use fake roots. the snapshot works as it records only changed blocks not the whole file system.

Of course when I try to unmount the root partition I can't! Then after this how is it possible to swap them back to get the original root partition back? I also have something that I don't understand. My root partition is 300M and has used about 170M of space. I created a 100M snapshot volume of it and it worked - how come it had enough space? How much space does a snapshot actually need, or more simply how does the snapshot work? I have read that excellent LVM howto, but these two points I don't fully understand and I don't think they are covered in more detail in the howto. Thanks a lot.
