1) Change the value of the "name" key in the pkginfo file.
2) Optionally edit the value of the "display_name" key.
3) Rebuild the catalogs with `/usr/local/munki/makecatalogs /path/to/repo`
The last step is crucial as the munki client tools do not interact with the pkginfo files at all; they only interact with the catalogs. Pkginfo files are the components used to build catalogs, but are not directly used themselves.
It's not clear if you want to remove a package from the munki server, or use munki to remove/uninstall a package from a client machine.
To remove a package from munki, just delete the pkginfo file (and optionally the pkg itself), then rebuild the catalogs with `/usr/local/munki/makecatalogs /path/to/repo`
To use munki to remove a package from a client, remove the name of the package from any managed_installs list for the client and add it to a managed_uninstalls list for the client.
