Are there any other programs from https://sourceware.org which say if "$HOME" is not defined, use "/" ? -- You are receiving this mail because: You are on the CC list for the bug.

...and when I ask bash to do this:
$ env - bash -c 'set -u ; echo $HOME' ; echo "command finished with exit code
$?"
The result is:
bash: line 1: HOME: unbound variable
command finished with exit code 127
Meaning that, the choice of how to react when an environment variable is
missing is a decision made by the program, it can report and error or it can
use an empty string and proceed or it can use some default like "/" and
proceed.
