Propose No. 5
Create a new database and namespace with resources and mapping in interoperability and install a module from the register into it, for example "dc-one-liners"

At the end of line No. 2 of the zpm installation:

set $namespace="%SYS" do ##class(Security.SSLConfigs).Create("ssl") set r=##class(%Net.HttpRequest).%New(),r.Server="",r.SSLConfiguration="ssl" do r.Get("/packages/zpm/latest/installer"),$system.OBJ.LoadStream(r.HttpResponse.Data,"c") zpm "install zapm" zapm "newdb dc-one-liners"

And you can create any number of such one-liners for all possible cases ;-)
