While prerm scripts can be maintained by humans, they are usually autogenerated
by one of the debhelper tools. That would explain why the file appears appear
neither in the Debian source tarball nor in source code. Please see attached
file glusterfs-server.prerm. Looking at the file's content, lines 8 through 12
say that they were autogenerated by dh_installinit. Looking at the
documentation for dh_installinit
(http://manpages.ubuntu.com/manpages/bionic/man1/dh_installinit.1.html), these
five lines were probably generated due to the presence of
glusterfs-server.upstart in the debian/ directory.

I launched a clean Ubuntu 16.04.4 machine on Amazon EC2 using the latest
available Xenial AMI. After I added the PPA and installed glusterfs-server
3.12, I see the file appear in /var/lib/dpkg/info/.

Did you check for the file after you installed the package and before
uninstallation? When I uninstall the package, the prerm file is deleted even
though the invoke-rc.d line writes out an error.

The file contains a systemd section for the new names of the Gluster services
(glusterd.service, glustereventsd.service, and glusterfssharedstorage.service).
That rules out that this file could have come from a <3.12 package as those
services were not created until 3.12.

Unless there is some subtle bug in my startup scripts, I have never installed
GlusterFS 3.7.6 on the Ubuntu machines that I use. I have always gone straight
to 3.12, without installing or upgrading from any older versions like 3.11 or
3.7.
