[pkg-apparmor] Bug#1107533: apparmor: initscript should exit quietly when package not installed

[Andrew Bower]

Package: apparmor
Version: 4.1.0-1
Severity: minor

Dear Maintainer,

I uninstalled apparmor and now get (ignorable) errors on boot:

  startpar: service(s) returned failure: apparmor ... failed!

Debian policy 9.3.2 says that initscripts "should not fail obscurely when the
configuration files remain but the package has been removed".

Typical initscripts would check for the presence of a server executable. In
this case I think we could just change how the lack of the shell functions is
handled.

Thanks,

Andrew
