[Pulp-dev] Pulp 2 and 3 Service Name Clashes

[Eric Helms]

Howdy,

In some migration of Pulp 2 to Pulp 3 cases, both will need to be ran
side-by-side on the same box. Given that pulp workers and pulp resource
manager are the same concept in both, this leads to their systemd resources
being named the same (or in today's case so slightly different enough you
can't tell them apart).

I'd like to propose a change to the service names to facilitate this
situation.


Option 1: Include Pulp version in Pulp 3 services

Example: pulp3-resource-manager

Pro: Explicit naming and understanding of new services.

Con: This locks services names to Pulp version, which will be odd with
semantic versioning if 4 or 5 comes along.


Option 2: Re-name Pulp 2 services to pulp2-

Example: pulp2-resource-manager

Pro: Explicitly identifies pulp2 services, easy to retro-fit by users onto
their setups or through RPM releases.

Con: Requires users to have upgraded to at least a particular Pulp2 version
to migrate to Pulp 3 (this may be required anyway).
