using rsync:

why not btrfs send | btrfs receive? is there some advantage to rsync?

did you hotswap the drives after each btrfs replace or shutdown and then swap?

what’s your host OS and do the drives spin down if inactive?

thanks for the writeup!

I’ve set up a local mail archive with just dovecot + imap plugin. you don’t need the full mail server with postfix and whatnot, as it’s not intended to send anything anywhere, or even receive anything for that matter. it just sits there ready to be searched with thunderbird, no need for other complex solutions you’ve mentioned.

this right here. remove partition and apply and then start the installer. there is a way to map this partition in the installer, but that’s such a horrific UX mess that it’s a challenge even for experienced folks.

I mean, OK, it’s a vulnerability and there are interesting implications, but this is hardly significant in any pracitcal sense of the word.

the potential victim has to run their system without a firewall, has to print to the printer they’ve never interacted with before and then the attacker can run shit with whatever the printing system’s user id is, which shouldn’t be an issue on any reasonably modern distro.

I routinely remove cups and friends from any system I run because I have no need for printing and it bothers me to see it constantly during every system upgrade.
