In Redhat (7.1 to be specific), how do you change the login in screen to say something other than what the version of RH is, the kernel, and the architecture of the machine?
Second, in the past I have noticed that this screen sorta automatically updates itself if it needs to. (I upgraded my kernel a little while back and it changed to tell me the kernel version.) Does anyone know how it does this?
You doing a command line login on redhat or something graphical? If its command line then have a look /etc/issue - this is normally rewritten at boot time to reflect the kernel version etc... You might also have /etc/issue.net which is used for network (telnet etc) prompts.
It's normally set in one of the startup scripts. It just runs 'uname' and a few other commands and pipes the output to /etc/issue. I'm not from the Redhat camp so can't say exactly where it is set but have a look in /etc/rc.d/???? and grep for mention of /etc/issue - that should find it.
