multiple versions of nix in the dependency tree

[dmah42]

our current Cargo.lock has 3 versions of nix listed, coming in from various dependencies

• libcontainer (auraed) pulls in 0.28
• deno (auraescript) is pulling in 0.26.2
• nix 0.24 is in the cargo.lock but i can't see where it's used

is this an issue?

I'm sure there are instances where this is not the case, but most of the time cargo takes care of this and if it becomes a problem, you get an angry compiler warning on cargo build. I think we can close this and someone can reopen another ticket once they hit a bad state

my main issue with it is compile time, rather than concerns around compatibility.
