Can you recover from that?
I imagine if you can mount from a busybox possibly
Then figure out the correct perms.
Eh, just hit it with the 777 and pray. Then swear at it some more.
Boot from a usb stick, mount the fs, use the live environment’s chmod command to fix stuff.
I think you'll need to change passwd and shadow, maybe a few other files, but besides that it'll mostly work.
This is the traditional method.
Yeah that's the painful part. A backup would be key here
Worst case you boot up a virtual server with the same OS as your own and just go down the tree learning permissions, and it’s a deep dive learning experience.
chrootin and then syncing the permissions from something like the equivalent offilesystempackage in Arch for your distro should get you going
