FYI with many routers, switches, and firewalls there are ways to automatically rollback changes in case the device is unreachable after applying them. Usually the command is called something like "Rollback".
You usually supply a time limit when you run the command and if you don't confirm the changes before that time limit it will rollback. So if you run rollback 30 and then do something which breaks the network connection, the config will rollback in 30 seconds. If it does work, you simply cancel the rollback.
As a linux noob, I am developing the spider sense of telling when a solution is something reliable and when it's something that will fuck me up 3 months down the line.
It's been... Interesting. I still haven't figured out what's the sane way to have multiple CUDA coexist peacefully...
…because of improper configuration and messing with system. The best way to heal is to make proper system backupand read the fucking manual.quit messing with the system.
I know it’s like asking a smoker to “just quit”, but…
this is why I keep my config as minimal as possible and everything I do is up on a GitHub repo
inb4 just use nix, cloning a repo and putting the right files in the right spots is something that can be scripted with relative ease and nix is way overkill unless you're using it for application deployments in money making incentives
Nixos is amazing, real immutability with absolute recovery.
Well.
Backups? Whats that! Is that where I store a copy of my config file? I havent modified mine in months. Life sure is breezy when I have no reason to tinker. Got so much of it.
Like how I used GDM-Settings on Pop_OS without knowing GDM-Settings is for OLD gdm, and now I have to use LightDM because I can't find the config files that are broken in GDM that cause it to have no styling and be black font with trails anytime something moves?
(and yes I have reinstalled it, gnome-shell, pop-theme, etc even with forcing dpkg to re-write over config files. I've manually gone through and deleted config files and reinstalled to redownload them, I cannot get GDM back to even default GDM let alone the pop version.)
See this is the exact sort of problem I always had with different flavours of Ubuntu. I’d always muck up my install with misconfigured shit and it would be too much time and effort to fix so I’d have to nuke the whole OS every now and then 😜
i have the opposite. i config everything that i understand even a single word from and reinstall the system if something goes wrong. I also got locked out of suse updates once bc messing with the repos. just restarted the vm and it worked
