Re: [linux-lvm] LVM2-Snapshot

Tried to apply the udm patch selection to vanilla 2.6.4 kernel recieved a shed load of failures and the kernel refused to build.  I am not a programmer so I have no clue how to rectify these issues.  do you have anything that works?

The snapshot target isn't in vanilla 2.6 yet, use my udm (unstable dm)
