Raspian, which runs my primary DNS, just corrupted my sudo file... Well fuck. Have to reformat, this time ill use arch.

@elgringo Can you shortly explain what you mean?

The post is very clear

You didn't take a backup.

@drRoss No, its not necessary. Its a application server, which runs pihole. The basic tasks are the same. The part about it is that i have to turn it off to fix it, no matter if i have backups. And in this time my internet does not really work.

@wolt I cant. How should i? raspian has diabled root.

@wolt A ok, but now i doesnt matter... I build a pfsense router.
So i wont need the rpi in the future.
