Is it possible to use Pkg3 with Julia 0.6?

I am trying to use Julia on a cluster where all of my persistent directories are accessed over NFS. Thus the package manager is basically unusable due to the well-documented slowness of Pkg2 on NFS.

Is it possible to install and use Pkg3 on Julia 0.6.3 to avoid this problem?

Unfortunately, I’m pretty sure the answer is no. Pkg3 relies on improvements in the internal package loading mechanisms which are only present in 0.7.
