From c403246424350bae14a30fc6a115608ca15f2aa1 Mon Sep 17 00:00:00 2001 From: Pablo Neira Ayuso Date: Sat, 2 Aug 2008 18:51:34 +0200 Subject: script: rework scripts that enable interaction with keepalived This patch reworks the documentation section. It removes the replicated keepalived.conf files and merge all the scripts into one to reduce confusion and improve maintainability. It's likely that the documentation directory will suffer more restructurations in the near future.
