I have worked out how to install packages as root, and access them them as an ordinary user (I just use ENV["JULIA_PKGDIR"]="/opt/julia/usr/share/julia/site/v0.3" as root to install, and as user to access the packages). But this doesn't work for IJulia, as it seems to need the file ~/.julia/IJulia/src/kernel.jl. This kernel.jl file is of course installed in my /opt/julia tree, but IJulia can't find it.
I can of course simply install IJulia as a user, but in general I like to keep my home directory only for personal (and config) files, and have everything else central. So - is there any way that I, as a non-root user, can run something like ipython notebook --profile julia --browser="firefox" and have julia pick up the kernel.jl file from the /opt/julia tree?
