This is a good one BEFORE the home drive is full. For this situation I thou=
ght about an interval. Because, if the user logs in and he downloads someth=
ing and then the home share is full, the user will not get any message.

You really shouldn't have PAM generate standard output for successful
logins. You will break things like SSH's SFTP.

We do something like this on our RHEL7 workstations, and we have
zenity pop up with a warning when they log in if their home
directory's quota is greater than 95% full.  It runs as an script
launched from a .desktop file in /etc/xdg/autostart/.

For console logins, I'd probably use a script in /etc/profile.d/ that
detected that it was a console login and generate all the output to
stderr, just in case.  But considering that people don't read the MOTD
I doubt they'd read warnings like that.
