For /etc/update-motd.d/30-sysinfo I noticed it likes to say my system is up 6 seconds and then when I check with uptime I notice it's wrong and has been up for hours or over a day.
Just curious if there is a reason for not doing it in a way similar to this?
function displaytime {     # we need dedicated function     local X=$(/usr/bin/uptime -p)     printf "Up time:       "     printf "\x1B[92m%s\x1B[0m\t\t" "$X" }

ok so on a quick search looks like there are some discrepancies on what the pam_motd is supposed to do and what it actually does

anyway this is how i fixed the problem on my armbian 
 
first edit the /etc/pam.d/login and /etc/pam.d/sshd and comment this line (in both files) 
session    optional   pam_motd.so  motd=/run/motd.dynamic noupdate and create a link from /run/motd.dynamic to /etc/motd/
ln -s /run/motd.dynamic /etc/motd reopen your session and the motd should be updated every time on login

Thanks Igor.  I figured as much.  I will try and work with the code, also taking into account vlad's analysis.  Will post results.  Oh, and fyi, my proposed solution also fell victim to the same bug today.  The bug can be confirmed by having the motd output the current time.
