Why would a manual deployment be new-style configId with a /car?

[Aaron Mulder]

So a change was made to the database portlet so when it deploys a new
pool it uses the configId user/database-pool-(name)/1/car

I don't really understand -- since this deployment doesn't use the
Maven tools, it's not packaged into a CAR or put into the repository,
right?  So this configId seems pretty bogus and I'm not sure why's
it's any better than setting the configId to just
database-pool-(name).  Any insight?

Thanks,
