Hi List,
Since my cry for (fairly minor) help here:
https://lists.debian.org/debian-user/2021/08/msg00461.html
I think I've dug myself into a bit of a deep hole.
After having overcome a fairly fundamental bug with calamares as described here:
https://github.com/calamares/calamares/issues/1564#issuecomment-846321060
And, (unnecessarily as it turned out) re-installed my system, I find
I'm unable to boot. ...
"Find the needle in the haystack" does not work for me:
1. It takes an unpredictable amount of time.
2. Meanwhile, operations are stopped.
3. Only one needle? Really?
4. How do I validate that the haystack is "correct"?
I keep my operating system images small enough to fit onto a single "16
GB" device (USB flash drive, SD card, SSD, HDD, etc.) using BIOS, MBR,
and no hardware or software RAID (lowest common denominator). I take
raw binary images of my operating system devices periodically and as
needed. I keep my operating system configuration files in a version
control system. I keep the vast majority of my data on RAID in a file
server. I snapshot, replicate, back up, archive, etc., everything and
rotate backup media on-, near-, and off-site. I have redundant and
spare hardware.
When a system image is damaged or doubtful, I restore the last raw
binary image onto a blank device, check out the configuration files, and
restore local data. The computer is back in operation in a predictable
amount of time with a high level of confidence that everything is correct.
