I'm reading about SysV init and I see there are levels 0-6.
I understand that level 4 could be defined by the OS operator for special purposes, but I'm having trouble thinking of any examples.
Has anyone seen runlevel 4 used in the wild? What was it used for? I assume a trigger for changing the runlevel to 4 also had to be created, since the system would never automatically go into level 4?
