Probably not, in most cases the error is #name being sent to nil, which is basically sloppy coding.

Do I need to provide my own “autostart” class if I want to try pharocloud (I’m guessing there is a startUp method somewhere that I need to override?)

If you do

ZnZincServerAdaptor startOn: 8080.

and save the image, the server will be there and running when the image comes back up.

This is how it has always been.

Since Seaside can work with multiple servers, you need to tell it what to you want.

PS: This is separate from Zinc that has a concept of managed servers, which are also kept running.

PS2: Technically, in both cases, the server are not really running all the time, they are stopped and restart automagically for you.
