       pam_issue is a PAM module to prepend an issue file to the username prompt. It also by default parses
       escape codes in the issue file similar to some common getty's (using \x format).

       Recognized escapes:

       \d
           current day

       \l
           name of this tty

       \m
           machine architecture (uname -m)

       \n
           machine's network node hostname (uname -n)

       \o
           domain name of this system

       \r
           release number of operating system (uname -r)

       \t
           current time

       \s
           operating system name (uname -s)

       \u
           number of users currently logged in

       \U
           same as \u except it is suffixed with "user" or "users" (eg. "1 user" or "10 users")

       \v
           operating system version and build date (uname -v)

       Add the following line to /etc/pam.d/login to set the user specific issue at login:

                   auth optional pam_issue.so issue=/etc/issue

       Only the auth module type is provided.
