On a Mac without the Linux kernel, setup ran `container system start
--enable-kernel-install` with a 120 s limit. That command downloads a
697 MB archive without printing anything, so most connections hit the
limit and the window showed `timedOut([...])`.
- Start the service with --disable-kernel-install (10 min: a first
start still pulls the 69 MB base filesystem).
- Download the kernel in its own step with progress, then hand the file
to `container system kernel set --tar ... --digest ...`, which checks
it against the runtime's digest.
- Opening the setup window no longer starts the download; Set Up does.
- Timeouts and runner errors read as sentences.
- A rebuild deletes the image it replaced, which frees about 2 GB each
time, and deletes or stops the builder VM unless it was already
running (it kept about 2.8 GB of memory).
- Setup asks for 10 GB free, measured on a real setup.
