Hi Keith,
I suspect this is done the the magic of PAM, but I haven't UTSL'd or anything. My guess is based
mostly on the fact that "man motd" on my Trusty machine references "pam_motd".

Thanks, Jonathon. mosh-server just copied what OpenSSH sshd does. Do you know
how OpenSSH knows it's supposed to print /run/motd.dynamic? (Does Ubuntu patch
it? Is there some other location to look at?) If
so, maybe we should take the same patch for the Ubuntu packages of mosh.
Cheers,
Keith

On Ubuntu (at least Trusty) machines the motd is split between
/etc/motd and /run/motd.dynamic . Note that Ubuntu Precise handles
this differently and /etc/motd is a symlink to /var/run/motd . So on
Trusty machines where mosh-server prints /etc/motd, it misses all
content in /run/motd.dynamic (on the athena dialups that is all motd
content, as none of it is in /etc/motd .) "man motd" on both Precise
and Trusty contains some useful information.
