The script

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 {{< /highlight >}}
