Subject: [PATCH] Zuo: patch zuo_process for "/bin/sh" on Guix
|
|
|
|
If:
|
|
|
|
1. The nonstandard but ubiquitous macro `_PATH_BSHELL` from
|
|
<paths.h> is defined; and
|
|
|
|
2. `zuo_process` is called with the exact path "/bin/sh"; and
|
|
|
|
3. The path specified by `_PATH_BSHELL` exists;
|
|
|
|
then `zuo_process` will execute the file specified by `_PATH_BSHELL`
|
|
instead of "/bin/sh".
|
|
|
|
Checking that the path specified by `_PATH_BSHELL` exists safeguards
|
|
against obscure errors if attempting to use stand-alone executables
|
|
built by the patched Racket in non-Guix envoronments.
