Is there a discussion somewhere of what the real stumbling blocks here are? It seems as though it comes down to... <zonepath> needs to be be mountable rw from the global zone. <zonepath>/dev needs to be rw,devices mountable from the global zone, then lofs mounted into the non-global zone. Yuck. <zonepath>/root needs to be rw mountable in the global zone (at least during install and uninstall) and non-global zone during normal operation. All of this seems rather straight-forward, except for the lofs mount. This could be worked around by rather than having a normal dev directory, a file "dev.ufs" is created. As the zone is being mounted, dev.ufs could be lofi mounted at <zonepath>/dev. At this point it is UFS, not NFS and can be lofs mounted into the non-global zone. Surely I am missing something else. What is it? Any interesting complications with patching and/or live upgrade?

It sounds like (at least based on the description) that the 'Filesystem driven device naming' project might be able to address /dev -- it implies that /dev would become a pseudo-fs that could perhaps be mounted in a zone (with only the correct devices visible for the zone). However, given the lack of public activity, I have no idea if it's even still alive. Perhaps someone more familiar with the project can comment? Alive? Dead? Pining for the fjords?
