laforge has submitted this change. ( https://gerrit.osmocom.org/c/osmo-gsm-manuals/+/30357 ) Change subject: merge gb-ns2 "chapters" in one ...................................................................... merge gb-ns2 "chapters" in one The files gb-nsw-{configuration-timer,configuration,maintenance} were not actually chapters, but sub-chapters or sub-sub-chapters. This breaks our general idea that all of those files are top-level chapters. It also breaks asciidoc validation on Debian 11: asciidoc: WARNING: gb-ns2-configuration.adoc: line 1: section title out of sequence: expected level 1, got level 2 asciidoc: WARNING: gb-ns2-maintenance.adoc: line 6: section title out of sequence: expected level 2, got level 3 the only place where they were used was the osmo-gbproxy manual, and there in the exact sequenc in which I now merged them over here.
