Hooks executed by Subversion are spawned with an empty environment. By default, not even variables like PATH will be propagated to them. In order to ensure that we're still able to find required executables, we thus write the current PATH variable into the hook script itself and then re-export it in t9164. This happens too late in the script though, as we already tried to execute the basename(1) utility before exporting the PATH variable. This tends to work on most platforms as the fallback value of PATH for Bash (see `getconf PATH`) is likely to contain this binary. But on more exotic platforms like NixOS this is not the case, and thus the test fails. While we could work around this issue by simply setting PATH earlier, it feels fragile to inject a user-controlled value into the script and have the shell interpret it. Instead, we can refactor the hook setup to write a `hooks-env` file that configures PATH for us. Like this, Subversion will know to set up the environment as expected for all hooks.
