Close. /etc/license does check /upgrade, but /upgrade is *not* used to
limit the number of logins. There's a kernel variable that stores the
number of users allowed on the system simultaneously, and it's checked
during login (through the use of a standard system call, "enhanced" by
Digital).
BTW, this is for Ultrix 2.0 and higher - Ultrix 1.2 handles login
limits differently.
