I'm not likely to be able to give you simple or complete answers to the complicated context --and I most definitely do not know your overall context or constraints. If FreeBSD can boot read-only media to some degree, which it can as I understand, the read-only boot pool might fit in that category for all I know. I've no clue how useful such would be to you. If you have no way to identify and fix potential corruptions, I'd expect you would initialize a new boot-pool, avoiding sources of potentially corrupt data. But I've no clue if you have snapshots, checkpoints, or other such for comparisons or if it would be reasonable for to you to back up in time if you do have some known-at-the-time good data, even if now old. Good luck --or at least better luck than landing in the disasterous-openzfs-import time frame in the first place. --=20 You are receiving this mail because: You are the assignee for the bug.=
