I have seldom come across unix multiuser environments getting used anymore for servers. Its generally just one user on one physical machine now a days. I understand run0's promise is still useful but i would really like to see the whole unix permission system simplified for just one user who has sudo access.
I've never understood the need for sudo(1) on single-user, physical machines: I keep a root shell (su(1)) around for admin tasks, and it's always been sufficient.
One password is easier than two and it feels weird to use the same password for both accounts. About half of my sudo invocations are 'sudo su' lmao.
You could probably save a process with `sudo -i`
