Public bug reported:
In performing install audits I noticed the following change to /etc/pam.d/login:
+ session optional pam_motd.so motd=/run/motd.dynamic
session optional pam_motd.so
Per man (8) pam_motd, this means that the scripts in /etc/update-motd.d are run
twice. One of these should use 'noupdate', like in /etc/pam.d/sshd:
# Print the message of the day upon successful login.
# This includes a dynamically generated part from /run/motd.dynamic
# and a static (admin-editable) part from /etc/motd.
session optional pam_motd.so motd=/run/motd.dynamic noupdate
session optional pam_motd.so # [1]
(It seems slightly odd to me that sshd will update /etc/motd dynamically
rather than /run/motd.dynamic, but that is not this bug)
