FOR WHO? AND WHY?
• Everyone who wants to learn something today
• Do something yourself instead of relying on a 3rd party app/system.
• Remove/Add system apps
• Modify DPI
• Backup/Restore apps to survive a dirty flash
• Apply a custom font
• Apply a custom bootanimation
• Install a new ringtone
• and so on.
Basically removing/adding system stuff can be easily done through a file manager but it takes time and we have to do it whenever we update a custom ROM.
Quote:
A couple of examples:
1. Customizing GApps packages: if you don't use all apps that are provided then you can simply remove them
2. Viper4Android: V4A is an awesome audio app and it's highly recommended to remove other audio apps/tweaks like AudioFX.
We will see how to add and remove system components. Once again, it can be done manually but your phone has to be booted into Android then it needs a reboot to apply the changes.
The last part is for the addon.d script. Your custom system changes will survive a dirty flash. No need to flash a zip file for each update 
WHAT DO YOU NEED?
1. A good file manager: MiXplorer, Solid Explorer, ES File Explorer (jk  )...
2. ZipSigner to sign your zip (or MiX Signer if you use MiXplorer // add-on available in the XDA thread)
3. A nandroid backup is recommended before using those scripts
4. Prepare your custom files: apk, gps.conf, ringtone, bootanimation,... Everything you want to add after a clean flash.
5. Free time. No young children around you
TEMPLATE AND MY CUSTOM ZIP
I'm a nice guy so I prepared a template. You can either download my own zip and customize it to your needs or use this template as a base to create your own zip "from scratch".
→ TEMPLATE: DOWNLOAD LINK (basic commands / you have to add your custom values: apps, paths of ringtones, bootanimation...)
→ MY ZIP: DOWNLOAD LINK (examples are always welcome to better understand an explanation. It can help to understand how to structure your files).
The template should be enough to start using a custom script.
SOME INFORMATIONS TO REMEMBER
Here are the paths of the main things we want to change in the /system partition (should work for most recent Android versions but check your system to be sure):
Quote:
• addon.d => backup script to survive a dirty flash (used by GApps package for instance)
• app and priv-app => system apps to add or remove
• etc => host file
• fonts => your font
• media => your bootanimation.zip
• media > audio > alarms => sounds for alarms
• media > audio > notifications => sounds for notifications
• media > audio > ringtones => sounds for ringtones
• media > audio > ui => sounds for various things such as low battery, unlock, camera,..
• root of /system for build.prop file
Files that have been removed will be installed again after a dirty flash.
Files that have been manually added will be removed after a dirty flash.
=> That's why we need a script to backup our modifications!

1/ It's a good practice to unmount then mount the partition before working on it.
Quote:
run_program("/sbin/busybox", "umount", "/system");
run_program("/sbin/busybox", "mount", "/system");
2/ Remove system components. Put a comma at the end of each line EXCEPT the last one.
Quote:
delete_recursive(
"/system/app/adaway.apk",
"/system/app/AdAway",
........................
"/system/priv-app/WeatherProvider",
"/system/priv-app/Tag"
);
3/ Extract the system files I want to install
Quote:
package_extract_dir("system", "/system/");
4/ Set the permissions for the files that I add
Quote:
set_perm(0, 0, 0755, "/system/addon.d/99-dirty.sh");
..............
set_perm(0, 0, 0644, "/system/priv-app/V4A-Magisk.apk");
5/ Same thing but for the /data folder (mount the partition > extract the data I want to add > set the permissions)
Quote:
run_program("/sbin/busybox", "mount", "/data");
package_extract_dir("data", "/data/");
set_perm(0, 0, 0755, "/data/local/afscript.sh");
6/ Unmount the modified partitions

run_program("/sbin/busybox", "umount", "/data");

PART 2: ADDON.D

1/ Files that I want to keep after a dirty flash
Quote:

CREATE YOUR FLASHABLE ZIP
The steps below are done with MiXplorer file manager.
1. Select all your folders and select Archive.
2. Confirm the creation of the archive file.
3. Enter the name of your file and select Store.
4. Your flashable zip has been created.
5. Select your zip file then Sign.
6. Select TESTKEY.
7. Your final flashable zip is created (xxx-signed.zip). This is the file you will flash from your custom recovery. You can safely remove the first zip file.
Thansk a lot the xda auther.
NOTES:
• your flashable zip has to be installed after a clean flash (or after wiping /system partition and making a dirty flash of your ROM custom). The updater-script will immediately remove/add the desired apps/folders. Leave your addon.d script alone. It will do its job without any user intervention.
Check your /system partition after the first installations to be sure that everything is working as expected.
• if you have something better to share or tips then let us know.
• all credits go to the people who shared their findings with the community. I picked up various information so this is more a general guide to create a custom updater-script and addon.d script.
• I recommend to keep an eye on the template or my zip when reading this guide.
