I have broken my #freebsd setup due to *not* upgrading bootcode after #zfs upgrade. Damn.

Seems like I can't gelli attach due to some erros in metadata, so I'm ready for reinstall.

But I want data from my old system, as I had yet to backup them (series of fuckups on my side).

I can't mount the old zroot on freebsd live usb drive becasue the filesystem is read-only. What should I try?
