From 3edf063d4d27d6132c67024b9560c0075fe7a48e Mon Sep 17 00:00:00 2001 From: Yuriy Andamasov Date: Wed, 6 May 2026 21:08:17 +0300 Subject: feat: flip swap mechanism on circinus — MD as primary, RST as override MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Mirror of #1899 for circinus. Same logic, same scripts, per-branch file set. Changes: - Rename docs/**/md-.md to docs/**/.md (drop md- prefix) for all 253 stems previously listed in docs/_swap.txt - Rename docs/**/.rst to docs/**/rst-.rst (add rst- prefix) for the same 253 stems - Repurpose docs/_swap.txt as docs/_rst_overrides.txt; initially empty - conf.py exclude_patterns flipped: rst-*.rst excluded by default - conf.py runtime-artifact references updated to _rst_override_state.json and _md_exclude.txt - scripts/swap_sources.py rewritten with inverted rename direction (rst-.rst → .rst when applying overrides; .md excluded via _md_exclude.txt) - scripts/import_myst.py and tests/test_import_myst.py deleted (obsolete) - tests/test_swap_sources.py rewritten for new semantics Identical change set to #1899 (current). Per-branch differences: - circinus has 253 stems vs current's 254 (suricata is current-only) - otherwise the script/conf.py/test changes are byte-identical with current Generated by robots https://vyos.io --- docs/configuration/interfaces/loopback.md | 67 +++++++++++++++++++++++++++++++ 1 file changed, 67 insertions(+) create mode 100644 docs/configuration/interfaces/loopback.md (limited to 'docs/configuration/interfaces/loopback.md') diff --git a/docs/configuration/interfaces/loopback.md b/docs/configuration/interfaces/loopback.md new file mode 100644 index 00000000..72f14c16 --- /dev/null +++ b/docs/configuration/interfaces/loopback.md @@ -0,0 +1,67 @@ +--- +lastproofread: '2026-01-23' +--- + +(loopback-interface)= + +# Loopback + +The loopback interface is a virtual, software-based network interface.
