5260325f | 5 | * This file performs some of the things login(1) normally does. We cannot |
6 | * easily use something like login -p -h host -f user, because there are | |
7 | * several different logins around, and it is hard to determined what kind of | |
8 | * login the current system has. Also, we want to be able to execute commands | |
9 | * on a tty. | |
