files can't be overriden

[dustymabe]

Currently if you put a file in:

• /run/console-login-helper-messages/motd.d/30_foo.motd
• /etc/console-login-helper-messages/motd.d/30_foo.motd

Then the contents of both files will get printed. Basically we don't allow for things to be overridden or canceled out, we just include it all.

This will probably be solved when we move to the native implementations of motd.d (#60) and issue.d (#7).

Looks like moving to the native implmentation of motd.d (#60) will solve this issue for motd via SSH (https://github.com/linux-pam/linux-pam/pull/69/files), but not motd via agetty --autologin (util-linux/util-linux@5a528e2).
Also might not work for issue.d (https://github.com/karelzak/util-linux/blob/d3f21dca1e4612cfd90e7a06dfabd6c767736ae6/term-utils/agetty.8#L127).
Thus, for issue.d and motd via agetty --autologin, if I'm understanding correctly, it might actually be easier to check for overrides under the current implementation of concatenating all .issue/.motd snippets into a final file to be read by agetty. It is unlikely that util-linux will support overrides upstream (util-linux/util-linux#1034 (comment)).
