Wanted to report from a state I could describe without confusion of steps= I had taken. Restored DD copy and ran `zpool import -fFX zroot` from the s= ame -current disk mentioned earlier and this time it did roll back a few mi= nutes and gave access to the corrupt filesystems. I must have touched it mo= re with an older copy every time though I thought that was not the first ti= me I started with -current. -X still is not defined in the manpage but is r= eferenced a lot online. I still have the disk copy that can be restored in the corrupt form if an= yone is interested in fixing issues such as scrubbing without the v28 rollb= ack taking place. The scrub was when it got stuck in a panic on import beca= use the scrub would resume and would cause a panic in doing so. Current was prone to occasional random crashes on my system so it took a = while to copy off the data in a successful run=2C though that may be my har= dware (which seems most stable after being up and running for a few hours u= nder full cpu load such as boinc). =
