+
+### 1.1.3. Gitea Action Runner Hardening
+
+The CI runners operate on a dedicated host system located in a completely separate Autonomous System (AS). This host is solely 
+dedicated to providing CI runners and does not perform any other tasks. Each runner is hermetically isolated from others using 
+non-privileged, shell-less user accounts with no direct login capability. Additionally, each runner executes within its own 
+separate directory tree, employs `DynamicUser` features, and adheres to strict systemd hardening policies (achieving a ``systemd-analyze security`` 
+rating of **``2.6``**). Docker containers used by runners do not run in privileged mode. Security is further enhanced through the use 
+of both UFW software firewalls and dedicated hardware firewall appliances.
+
+## 1.2. Match Host and Target Versions
+
+Build, for example, a Debian Trixie live image only on a Debian Trixie host. The build toolchain and boot artifacts are 
+release-specific: ``live-build``, ``live-boot``, ``live-config``, ``debootstrap``, ``kernel/initramfs`` tools, ``mksquashfs``, 
+``GRUB/ISOLINUX``, and even ``dpkg/apt`` often change defaults and formats between releases (e.g., compression modes, SquashFS 
+options, hook ordering, systemd/udev behavior). Building on a different host release commonly yields non-reproducible or even 
+unbootable ISOs (missing modules/firmware, ABI mismatches, divergent paths). Keeping host and target on the same version ensures
+reproducible builds, matching dependencies, and compatible boot artifacts.
+
+## 1.3. Immutable Source-of-Truth System

 source-code definitions. All configurations, system components, and installation routines are embedded during build time and

 * **Rationale**: These options enforce strict error checking and handling, reducing silent failures and ensuring 
 predictable script behavior.
 
 # 4. Prerequisites
 
-* **Host**: Debian Bookworm or newer with `live-build` package installed.
+* **Host**: Debian Trixie with `live-build` and ``debootstrap`` packages installed.
 * **Privileges**: Root or sudo access to execute `ciss_live_builder.sh` and related scripts.
 * **Network**: Outbound access to Debian repositories and PTB NTPsec pool.

+#   Directory where mailboxes reside, _or_ name of file, relative to the
+#   home directory.  If you _do_ define MAIL_DIR and MAIL_FILE,
+#   MAIL_DIR takes precedence.
+#
+#   Essentially:
+#      - MAIL_DIR defines the location of users mail spool files
+#        (for mbox use) by appending the username to MAIL_DIR as defined
+#        below.
+#      - MAIL_FILE defines the location of the users mail spool files as the
+#        fully-qualified filename obtained by prepending the user home
+#        directory before $MAIL_FILE
+#
+# NOTE: This is no more used for setting up users MAIL environment variable
+#       which is, starting from shadow 4.0.12-1 in Debian, entirely the
+#       job of the pam_mail PAM modules
+#       See default PAM configuration files provided for
+#       login, su, etc.
