Bug Description

This could either be in libpam0g or libpam0g-modules, not sure.

 I have a fresh Ubuntu 14 install with the latest pam_motd. I added a cool shell
script in /etc/update-motd.d/99-coolStuff

Verified correct syntax. doing a run-parts . from that dir gave me correct results. But the correct results didn't show up when logging in. Eventually I figured out camel casing the file name breaks pam_motd. :(

99-coolstuff works fine from login.

Not sure if this is by design, but run-parts didn't care and I thought this emulated the behavior of that package- at least that's what your documentation says. Speaking of docs- there is SO much stale info about the old update-motd package out there that it took an obnoxious amount of time to figure out what package this was in. An update to this man page saying it isn't done in cron and update-motd has been superseded by this would be good.

It's not by design. But I also don't think it's a bug in pam_motd, but in
run-parts itself. pam_motd invokes run-parts with --lsbsysinit, which is
documented as:

       If the --lsbsysinit option is given, then the names must not end
       in .dpkg-old or .dpkg-dist or .dpkg-new or .dpkg-tmp, and must belong
       to one or more of the following namespaces: the LANANA-assigned
       namespace (^[a-z0-9]+$); the LSB hierarchical and reserved namespaces
       (^_?([a-z0-9_.]+-)+[a-z0-9]+$); and the Debian cron script namespace
       (^[a-zA-Z0-9_-]+$).

Your example name, '99-coolStuff', does match the last of these, so should
not have been skipped.

I don't think it's the place of the manpage to document what things are *not* true. Better to fix any wrong documentation claiming this is being done via cron.
