@k900:0upti.meK900Honestly18:05:25
@k900:0upti.meK900If you can get physical access to the machine18:05:29
@k900:0upti.meK900And it doesn't require, like, driving to a data center18:05:35
@k900:0upti.meK900Just reinstall18:05:36
@k900:0upti.meK900It's not worth the trouble18:05:39
@rvdp:infosec.exchangeRamses 🇵🇸Unless you do it for educational purposes, I agree18:06:14

If you can get physical access to the machine
Yeah, but this is practice for when such physical access is too much of a pain.

@k900:0upti.meK900Uhh18:06:41
@k900:0upti.meK900If you actually have a production system you have to attempt this on18:06:53
@k900:0upti.meK900You have a MUCH bigger problem18:06:57
@k900:0upti.meK900 btrfs convert is something you do as a joke 18:07:15
@k900:0upti.meK900Not something you do to systems you care about18:07:24

If you actually have a production system you have to attempt this on
Sorry, I should have clarified. It is "in production" but even the production instance is just mostly for education purposes. If I mess it up I will only be mad at myself (and nobody else will be mad at me).

@k900:0upti.meK900What I'm saying is, this is not a thing you should be practicing18:09:01
@k900:0upti.meK900If anything, the thing you should be practicing is never getting into a situation where you need to do this18:09:18

What I'm saying is, this is not a thing you should be practicing
Yeah, you are probably right. Maybe better for me to figure out how to more automate a reinstall which uses btrfs and disko instead.

@k900:0upti.meK900What you're saying right now is "I'm going to practice building a campfire while being attacked by 30-50 feral hogs"18:10:20
@k900:0upti.meK900Like18:10:24
@k900:0upti.meK900Your problem isn't the campfire18:10:27
@k900:0upti.meK900If you're in that situation18:10:32
@k900:0upti.meK900You can probably figure out a campfire if you get rid of the feral hogs18:10:47

If you're comfortable with kexec'ing into an image in memory, then it's doable. If you've never done that before, then I'd make sure that you're able to get to the machine in case you mess up
do you have a good reference for how I might do the kexec'ing into an image in memory part? I am trying to understand how that is different than the "unmount root without reboot" link above. Will kexecing into an image possibly give me the full effect of as if I had booted into a live thumbdrive?
