in addition to the case of my previous email, libos is not limited to run on user-mode: it is just a library which can be used with various programs. thus it has a potential (not implemented yet) to run on a hypervisor like OSv or MirageOS does for application containment, or run on a bare-metal machine as rumpkernel does. We already have a clear interface for the underlying layer to be able to add such backend.
again, it's not only for user-mode.
mixing all the stuff in a single architecture may not only mislead to users, but also introduce conceptual-disagreements during code sharing of essential parts.
I don't see any benefits to have a name 'um' with this idea.
# I'm not saying sharing a part of code is bad idea at all, btw.
