Subject: [PATCH] um: Makefile: use bash from the environment
Date: Fri,  2 Feb 2024 19:56:33 +0000	[thread overview]
Message-ID: <20240202195645.3224648-1-shamrocklee@posteo.net> (raw)

Set Makefile SHELL to bash instead of /bin/bash for better portability.

Some systems do not install binaries to /bin, and therefore do not
provide /bin/bash. OS distributions such as NixOS and Guix System
intentionally avoid implementing the Filesystem Hierarchy Standard (FHS).

The recipies inside arch/um/Makefile don't require top-level Bash to
build, and setting "SHELL" to "bash" makes Make pick the Bash executable
from the environment[2], hence this patch.
