running CBE on RAM vfs

Hello Genodians

As a precursor of running CBE on our i.MX8 IoT device, I'm trying to run CBE entirely from RAM based in a vfs and testing it using the block_tester. To achieve this I merged the vfs_cbe_init and vfs_cbe runscript using a sequence to run cbe_init before vfs_cbe.

My problem is that the cbe/current/data device seems to be only 4 KiB or 1 block in size, regardless of how I parameterize cbe_init.

Any ideas on why this happens or how to fix it?

For reference, my runscript repos/gems/run/vfs_cbe_ram.run is available on the following branch: https://github.com/throwException/genode/tree/cbe_ram

Best regards Stefan
