Ha-ha! I like it!

Does anybody remember LIDS:

https://en.wikipedia.org/wiki/Linux_Intrusion_Detection_System

The name is a bit deceptive. In short, LIDS is Linux kernel patch that
(roughly speaking) does the following: after boot process finishes, and
all services have been started root user is demoted to user nobody ;-) You
can only do administration on cold powered off system - i.e. off line.
Alas, LIDS didn't make into main stream kernel. Its competitor (?) SElinux
made it instead, and SElinux is child's play compared to LIDS IMHO...
Every time SElinux is mentioned in one respect or another it makes my day,
as I remember LIDS ;-)

I hope, someone has few loughs with me here.
