Subject: [PATCH 1/3] core: log if the service to activate vanished before we
 activate it

Normally this shouldn't happen unless the daemon is reloaded.

A similar check is already in place in socket.c for the socket
activation case.

This hopefully makes #1526 non-fatal, though it will not fix this, and
there's something else to fix.

Subject: [PATCH 2/3] tty-ask-password-agent: don't warn if we cannot disable
 wall messages on the calling tty

For example, due to perm issues.

THis simply downgrades the message about it, since this is purely
cosmetical anyway.

Fixes #1543.

Subject: [PATCH 3/3] unit: remove [Install] section from the user exit.target
 unit

There's no concept of ctrl-alt-del for user systemd instances, hence
don't suggest it woud make sense to symlink the unit to it.

Fixes #1525.
