Note: "permalinks" may not be as permanent as we would like,
direct links of old sources may well be a few messages off.


> Here, it tells LVM2 can be used for creating snapshots.

Caution: LVM2 snapshots become very slow if the amount of changes 
increases due copy-on-write. Add the additional seeks and you have a 
much lower write speed left.
The last time I tried it reduced the write speed to 15% of the normal 
throughput.
