It seems some shells linked to /bin/sh don't have consistent behavior
with error codes on execution failures. Explicitly use /bin/bash so that
"not found" errors are correctly generated. Repeating the comment from
the test:
/*
* Execute as a long pathname relative to "/". If this is a script,
* the interpreter will launch but fail to open the script because its
* name ("/dev/fd/5/xxx....") is bigger than PATH_MAX.
*
* The failure code is usually 127 (POSIX: "If a command is not found,
* the exit status shall be 127."), but some systems give 126 (POSIX:
* "If the command name is found, but it is not an executable utility,
* the exit status shall be 126."), so allow either.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
