Synopsis

patchall recurses a set of directories looking for executable files that need be fixed to work on NixOS. Specifically, these files include:

• ELF executables whose dynamic loader does not exist. patchall sets the dynamic loader of these files to the dynamic loader currently used by the patchelf binary itself. It does this by calling NixOS patchelf utility which must be in your $PATH.
• Shebang scripts with an interpreter other than /bin/sh or /usr/bin/env but whose interpreter is somewhere under /{bin,sbin,usr,lib,lib64}. patchall sets the shebang to /usr/bin/env $INTERPRETER $ARGS where $INTERPRETER is the original interpreter with the path removed and $ARGS is the original set of arguments. For instance #!/sbin/somewhere/my-cool-tool foo bar becomes #!/usr/bin/env my-cool-tool foo bar.
