haskellPackages.stack: enableSharedExecutables = false; #20133
Conversation
The `stack` binary has a large number of dependencies, and therefore loads a large number of shared objects on startup (I count 20,000 `open` syscalls with `strace` when running `stack --version`). Statically linking haskell dependencies brings the time taken for `stack --version` from 1.3 seconds to 0.006 seconds on my machine. I think it's worth it, since the binary is frequently invoked for short operations during a dev workflow.

this is the only actual change, the rest is just automatic trailing whitespace removal (feel free to disregard it of course)

When I install @anderspapitto Do you know what I need to do to get a statically linked one via nix? (ATM I'm manually downloading the statically linked executable from the stack github release page.) Edit: $ nix-instantiate --eval '<nixpkgs>' -A lib.nixpkgsVersion
