Creating a custom Percona XtraDB Cluster .deb

I’m looking to repackage Percona XtraDB Cluster with a few tweaks for our Debian systems.

I saw that debian build tools were available in the build-ps directory of the Launchpad percona-xtradb-cluster/5.6 repo. However, I’d prefer to build from the released 5.6.15 source tarball rather than from latest. Would this simply be a matter of using the build-ps tools available in the repo with the source tarball, or is there more that needs to be done?

The docs just say there are examples for building .deb files in the packaging/percona directory, but that does not appear to be the case any longer.

Any help appreciated.
