yesterday I suggested in this topic: Rustup offline network the use of CVMFS to distribute tools for working with rust.
CVMFS is a read-only file system that – once mounted in the client machine – provide access to the whole software stack installed in the server.
It is used mostly inside CERN and other big experiments to distribute software inside the datacenter.
Maybe could be interesting to run the same infrastructure to distribute rust and its toolchains.
It will allow to basically have any version of rust in your local machine without installing it first, at the cost of downloading whatever files are necessary from the network when you need them.
Is it something the community could find useful? Should I provide such service?
