## 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
