So it seems that is failing somewhere. Do any other VNFS images work?
If you want to go in... you can extract the transport-http capability, and edit the wwgetvfs script that's contained within. Remove that "2>/dev/null" from that command, rebuild the capability file, and then rebuild the bootstrap. That would hopefully point you to what's actually throwing an error.
The ID always being 5 is correct. If it changed I would be worried. That should be the Database ID of the VNFS.
