No. The beauty of Linux (or actually, UNIX) is that you have userspace. Despite UNIX being so fucking beautiful, nowadays every retard that asks Claude to write something they can take credit for needs administrative system privileges. That's probably the worst thing that happened. Ever.
Because unless you're using permissioned kernelspace, you don't need root. And no, you don't need systemd.
I think this is a bit over my head
Just think like this: every time you do sudo <command> it means that <command> can read everything on your box, including that secret directory you just did chmod 600 on.
I don't think you can avoid using it fully, but just think of the above every time you type sudo.
example:
# id -a
uid=0(root) gid=0(root) groups=0(root)
# ls -lrt /home/opti/.ssh
total 20
-rw------- 1 opti opti 399 Feb 5 13:37 id_ed25519
-rw-r--r-- 1 opti opti 94 Feb 5 13:37 id_ed25519.pub
-rw-rw-r-- 1 opti opti 49 Feb 5 13:39 config
-rw-r--r-- 1 opti opti 928 Feb 6 20:59 known_hosts
# cat /home/opti/.ssh/id_ed25519 | wc
7 13 399"oh shit root just counted the characters in my private key"
"oh shit root just counted the characters in my private key"
but how? by using sudo
(sorry for dumb questions)
sudo means: execute the following command as root. (it means "superuser do", because before sudo we only had su - "superuser", without the... do)
opti@server:~$ id -a
uid=1000(opti) gid=1000(opti) groups=1000(opti)
opti@server:~$ sudo id -a
uid=0(root) gid=0(root) groups=0(root)
Hahahaha I thought that was the beauty of Linux!?
