+  etc-update script for alpine linux
+---
+
+Alpine linux doesn't seem to have a tool to merge pending configuration changes, so I wrote one : 
+{{< highlight sh >}}
+#!/bin/sh
+set -eu
+ 
+for new_file in $(find /etc -iname '*.apk-new'); do
+    current_file=${new_file%.apk-new}
+    echo "===== New config file version for $current_file ====="
+    diff ${current_file} ${new_file} || true
+    while true; do
+        echo "===== (r)eplace file with update?  (d)iscard update?  (m)erge files?  (i)gnore ====="
+        PS2="k/d/m/i? "
+        read choice
+        case ${choice} in
+            r)
+                mv ${new_file} ${current_file}
+                break;;
+            d)
+                rm -f ${new_file}
+                break;;
+            m)
+                vimdiff ${new_file} ${current_file}
+                break;;
+            i)
+                break;;
+        esac
+    done
+done
