Update the reStructuredText anchor and cross-reference to match the variable name.

The anchor on line 58 of docs/user/settings.rst uses .. _vpn_domain: while the environment variable is named OPENVPN_DOMAIN. This inconsistency should be resolved by renaming the anchor to .. _openvpn_domain:. Additionally, the cross-reference in docs/user/quickstart.rst:58 that uses :ref:OpenVPN <vpn_domain> must be updated to `:ref:`OpenVPN <openvpn_domain> to maintain the working reference.

Changes required

In docs/user/settings.rst line 58:

-.. _vpn_domain:
+.. _openvpn_domain:

In docs/user/quickstart.rst line 58:

-<vpn_domain>` services.

🤖 Prompt for AI Agents 
In `@docs/user/settings.rst` around lines 58 - 61, Rename the reST anchor ..
_vpn_domain: to .. _openvpn_domain: in the settings documentation and update the
corresponding cross-reference :ref:`OpenVPN <vpn_domain>` to :ref:`OpenVPN
<openvpn_domain>` so the anchor name matches the environment variable
OPENVPN_DOMAIN and the reference resolves correctly.

# Check the shebang and content of the file

Repository: openwisp/docker-openwisp

Length of output: 1216

Fix POSIX shell incompatibility: use [ ] instead of [[ ]].

Line 32 uses bash-specific [[ ]] test syntax, but the shebang is /bin/sh. This will cause a syntax error in dash (the default /bin/sh in most container environments). Replace with the POSIX-compatible [ -z "$OPENVPN_DOMAIN" ].

Suggested fix 
-	if [[ -z "$OPENVPN_DOMAIN" ]]; then exit; fi
+	if [ -z "$OPENVPN_DOMAIN" ]; then exit; fi

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

🤖 Prompt for AI Agents 
In `@images/common/init_command.sh` at line 32, The test using bash-only [[ ]]
around OPENVPN_DOMAIN is incompatible with the /bin/sh shebang; replace the
conditional in the init script that checks OPENVPN_DOMAIN (the line using [[ -z
"$OPENVPN_DOMAIN" ]]) with a POSIX-compatible test using [ -z "$OPENVPN_DOMAIN"
] and ensure proper quoting and an exit (e.g., exit 1) remains after the test to
preserve behavior in the init_command.sh flow.
