All that happened is that some functionality in mdadm was moved into lvm2 as that was the major user of that functionality. IIRC disk encryption was the other user. All lvm users here with up to date systems already did this step without trouble, so you can proceed as usual. As you are modifying some low level vital functionality, the usual precautions will apply: ensure that no-one reboots the machine while you are doing this, notebook batteries must not die in the middle, no power outages. And do everything in a single terminal session. -- alan dot mckinnon at gmail dot com
