weird... reproduced. code is: v.mkString(state.settings.restrictEval || state.settings.pureEval ? "" : getEnv(name).value_or(""));
It looks like HOSTNAME is something Bash provides but not a standard environment variable. ZSH and Fish doesn’t have it.
ohhh
Ugly hack it is. let hostname = builtins.readFile ./whereami; hostConfigPath = ./${hostname}; hostConfig = if builtins.pathExists hostConfigPath then import hostConfigPath else {}; in
