How critical is it for the system to delete the nobody user?

Question

linux

Being on the first steps of studying *nix -s, in a fit of research paranoia, I found the
user nobody in the passwd. I was in a hurry and before I knew that this was a harmless *nix autouser with minimal access rights to open and examine suspicious codes, I demolished this user with the userdel -f command
Question: how critical is it for the system to delete nobody and should I add it immediately Or can I live without it until I need to work with suspicious codes? Does the absence of nobody somehow affect the security of the system on the network?

Answer 1

Любой юзер, кроме root, некритичен.
Максимум возможных у вас проблем - не будут работать сервисы (например, апач любит от имени этого юзера работать). Но это решится их (сервисов) переустановкой.
