In my opinion, although I undestand why Underhill project decided to come up with the original VTL kernels separation during build time, it's time to reconsider this approach and to come up with a more generic design, supporting booting the same kernel in different VTLs. The major reason for this is that LVBS project relies on binary compatibility of the kernels running in different VTLs. The simplest way to provide such a guarantee in both development and deployment is to run the same kernel in both VTLs. Not having this ability will require carefull crafting of both the kernels upon build, making kexec servicing of such kernels in production complicated and error prone. Thanks, Stas
