My detective work is limited to putting 1 and 1 together, your posts in this case. Anyway, let's hazard a guess at what the scenario might have been. 1 Debian 11 was running from sdc2 as root (ie /, not /root). 2 You removed a USB stick without unmounting it. 3 You typed reboot (or equivalent) intending to run another OS, but things didn't get that far. 4 Closing down Debian 11 was taking too long, maybe because of 2. 5 You powered off by holding down the power button. 6 You now get the symptoms described earlier. So would this be roughly equivalent to how one should recover a BTR filesystem's integrity after a power cut happens? If this is so, it might be worth describing things in those terms, and posting under a Subject like: Recovering a BTR filsystem after a power outage. As for the last clause of your earlier post, I think you'd have to give some idea of the disposition of your Debian system; whether directories are spread over more than one partition, and hence which settings would be affected were you to reinstall. Cheers, David.
