tlug: xdm and 'nologin' on Slackware

[Jim Schweizer <schweiz@example.com>]

Hi all,

I had thought there was a way to disable any new login attempts
into a system by simply creating a file called /etc/nologin.

Supposedly, it can have a null file size or a message can be 
placed into the file informing the status of the system. If a
user attempts to login remotely, a message should be displayed
with contents of the /etc/nologin file, and then disconnect the
user.

But, on Slackware running xdm if you create the file then
reboot, the nologin file vaporizes and regular logins are allowed

Hmmm, since xdm runs as root, is /etc/nologin not a valid option?

Regards,

Jim S.
