Manjaro seems to install both bash (login shell) and zsh (user preferred shell, e.g. when opening a console).

The posix standard demands that the SHELL env var points to the user's preferred shell:

This variable shall represent a pathname of the user's preferred command language interpreter. If this interpreter does not conform to the Shell Command Language in the Shell and Utilities volume of IEEE Std 1003.1-2001, Chapter 2, Shell Command Language, utilities may behave differently from those described in IEEE Std 1003.1-2001.

However, SHELL still points to bash. This env var is commonly set by login on unix systems, but that doesn't mean that's the only place supposed to set it.

This impacts user-visible behavior of my installer: https://gitlab.haskell.org/haskell/ghcup-hs/-/issues/302

Note that I'm not a Manjaro user and am not running any Manjaro system, so I cannot provide technical feedback or system information.
