I accidentally untarred archive intended to be extracted in root directory, which among others included some files for /etc directory.
I went on to rm -rv ~/etc, but I quickly typed rm -rv /etc instead, and hit enter, while using a root account.
This is why you should setup daily snapshots of your system volumes.
Btrfs and ZFS exist for a reason.
Wish ZFS didn’t constantly cause my proxmox to need to be forcefully restarted after the ZFS pool crashed randomly.
That or make your system immutable
That’s my current approach. Fedora Atomic, and let someone else break my OS instead of me.
