I've written the following Emacs package debug script which can be
run by `$ bash /home/werner/.emacs.d/debug/.emacs.d/init.el`:

```emacs-lisp
#!/usr/bin/env bash
:;# $ realpath init.el
:;# /home/werner/.emacs.d/debug/.emacs.d/init.el
:; HOME=$(dirname $(dirname $(realpath -e $0))) proxychains-ng-socks5 /usr/local/bin/emacs -- "$@"; exit

;;Bootstrap straight
(defvar bootstrap-version)
(let ((bootstrap-file
(expand-file-name "straight/repos/straight.el/bootstrap.el" user-emacs-directory))
(bootstrap-version 5))
(unless (file-exists-p bootstrap-file)
(with-current-buffer
(url-retrieve-synchronously
"https://raw.githubusercontent.com/raxod502/straight.el/develop/install.el"
'silent 'inhibit-cookies)
(goto-char (point-max))
(eval-print-last-sexp)))
(load bootstrap-file nil 'nomessage))
(straight-use-package 'use-package)
(setq straight-use-package-by-default t)

(use-package company
:demand t
:hook
(after-init . global-company-mode))
```
But the `proxychains-ng-socks5` wrapper script relies on the normal HOME variable setting. How to solve this dilemma?

Well, you /could/ derive your version of HOME differently. Yes, let's go
with that.

Initially, HOME is derived from the 6th field in the user's
/etc/passwd entry. You could
- use whoami(1) to determine the username
- use grep(1) and cut(1) (alternately, just awk(1) )to parse /etc/passwd
and extract the home directory of the selected username
- use that extracted home directory value to set your HOME variable

Please elaborate on what the abnormal HOME variable contents are?

Are you artificially changing the HOME variable's contents at the start
of the script? It looks like it's commented out to me. (But I don't
speak LISP.)

I'm failing to fathom a case where the contents of HOME would not be normal.

Some software uses /etc/passwd instead of the HOME variable.
It's a bug.

Possibly you can inspect 'proxychains-ng-socks5' if it's an script and
fix the bug yourself.

That bug was very common in the past. Fortunately nowadays most
software has fixed it. Ivan Shmakov commented about that in
comp.emacs a pair of years ago:

Ivan Shmakov <ivan@siamics.net> on comp.emacs
Message-ID: <8736wyx2p2.fsf_-_@violet.siamics.net>

Unfortunately, some software refers to passwd(5) data directly
instead, leaving no way for the user to override the home
directory location. In particular, this was the behavior (IIRC)
of programs based on older Glib versions. And I vaguely recall
that Emacs might have been affected as well.
