#14070 Use immutable_inputs for `PEX`s New issue created by stuhood #13848 (designed in #12716) added support for immutable process inputs, which are symlinked into the sandbox, rather than copied there. Once immutable inputs have stabilized (notably, once #13899 is fixed), we should provide the

repository.pex

as an immutable input to significantly reduce IO. It's also possible that in most cases where a PEX is used as an input to a process, that supplying it as an immutable input would make sense: in particular, cases where a PEX contains only thirdparty code, and firstparty code is materialized as loose files. pantsbuild/pants
