vbox6-block: no policy defined for label 'vbox6-block -> block0'

I'm struggling to understand how to configure the vbox6-block component.

All seems to go well until...

[runtime -> ahci-0.part_block] Warning: no policy defined for label 'vbox6-block -> block0'

I read up on component configuration; I have a better understanding of it now. https://genode.org/documentation/genode-foundations/22.05/components/Compone...

But I don't understand the details of how to configure block services in a launcher.

For detailed logs, my launcher config, etc., see: https://github.com/dckc/madmode-blog/issues/49#issuecomment-1407819827

p.s. I got falkon and screenshot working, but in that same issue 49, note problem reports w.r.t - shutdown / acpica - ssh_client - sneakernet (usb_drv)
