This uses the systems default shell:
- Ubuntu: dash
- Fedora: bash
Since bash is invoked via /bin/sh, it operates in POSIX mode:
https://tiswww.case.edu/php/chet/bash/POSIX
- remove '# Ignore the expand_aliases command in zshell.'
Not needed because the shell operates in POSIX mode
- [[ is bashism -> use [
- autostart_files=( $autostart_file_match )
is not supported in dash, so use 'ls'
- shellcheck runs the dash flavor, since dash is a minimalistic shell.
Tested on dash & bash.
This insures the common exception handler will not be
re-entered. The handler does not support nested interrupts
and the interrupt stack pointer and context will be overwritten
resulting in hard to debug hardfaults.

preemption. The startup code defaults all the priorities
to the same value 128.
