Bug ID: 250081
Summary: no way to display immutable motd when update_motd="NO"
and /var/run is tmpfs
Product: Base System
Version: CURRENT
Hardware: Any
OS: Any
Status: New
Severity: Affects Some People
Priority: ---
Component: bin
Assignee: b...@freebsd.org
Reporter: guy...@gmail.com
r350184 changed login(1) to read /var/run/motd.
As been noted in
https://lists.freebsd.org/pipermail/svn-src-head/2019-July/126776.html
there is a need to support displaying an immutable motd with specific exact
text at login.
To keep motd immutable and prevent it being prepended with uname output,
update_motd needs to be set to "NO" in rc.conf to not generate /var/run/motd.
An immutable motd file can then can be created in /var/run
but if it is a tmpfs, the file will not survive a reboot.

Phabricator review to change login(1) back to reading /etc/motd.
This allows using /etc/motd as a regular file when update_motd="NO".
update_motd="YES" causes /etc/motd to be created as a symbolic link to
/var/run/motd so login(1) will still read it.
