Please help me with this debloat flashable zip - Android Q&A, Help & Troubleshooting

Hello Everyone
I created a small flashable zip in order to remove the apps I don't want COMPLETELY from /system/app but for no apparent reason it doesn't remove anything.
Here's what I have wrote inside the updater-script file :
Code:
unmount("/system");
unmount("/data");
unmount("/preload");
ui_print(" ");
ui_print("Mounting partitions..");
run_program("/sbin/mount", "-t", "auto", "/system");
run_program("/sbin/mount", "-t", "auto", "/data");
run_program("/sbin/mount", "-t", "auto", "/cache");
ui_print("Partitions mounted.");
ui_print("Starting debloat process..");
ui_print("Removing apps from /system/app");
delete_recursive("/system/app/BookmarkProvider");
run_program("/sbin/rm", "-rf", "system/app/Browser");
run_program("/sbin/rm", "-rf", "system/app/FaceUnlockService-res");
run_program("/sbin/rm", "-rf", "system/app/NfcNci");
ui_print(" ");
ui_print("Removal Process Finished.");
ui_print(" ");
ui_print("Cleaning Cache");
run_program("/sbin/rm", "-rf", "/cache");
ui_print(" ");
ui_print("Unmounting partitions: /system /data /cache");
unmount("/data");
unmount("/cache");
unmount("/system");
ui_print(" ");
It's mind boggling because the script runs flawlessly when I flash it through Recovery except it doesn't remove ANYTHING!
Some one please tell me what am I doing wrong here?
I've also attached the flashable zip file.
Device : Samsung Galaxy Note 3
Rom : LineageOS (Rooted with Magisk)
Recovery : TWRP 3.4.0-1 (Latest)
Busybox : Installed through Magisk.
Thanks.

Excerpt of known commands in OTA updater-script
unmount
Syntax
unmount <mount_point>
Description
Unmounts the filesystem mounted at mount_point.
run_program
Syntax
run_program <program-file> [<args> ...]
Description
Run an external program included in the update package.
delete_recursive
Syntax
delete_recursive <file-or-dir1> [... <file-or-dirN>]
Description
Delete a file or directory with all of it's contents recursively.
mount
Syntax
mount <fs_type, partition_type, name, mount_point>
Description
Mounts a filesystem of fs_type at mount_point. partition_type must be one of these: system , userdata, etc.pp.
This in mind the main failure in your script is misuse of run_program, IMHO

Spoiler
Mount.
You could test those using terminal first...
But why not just use TWRP's file manager?

Can you please point out to where the problem comes from precisly and what's wrong with the run_program command I wrote? Sorry I'm total noob

I appreciate your help but I still cannot figure it out. This is just a snip from a big list of apps that I try to debloat so that's why I created this flashable zip.

Deleting those with file manager is much faster than typing that script...
How about mounting them first in TWRP and then running the script? Of course edit it 1st so it skips the mounting part...
BTW, yours looks like very much like this one.
Easy debloat script for Oreo Stock ROMs
I haven't seen anyone post any easy debloat script, so here is my personal one for N8. This is made for OREO - but it will work for Nougat-based ROMs too, as long as the file names haven't been changed. This could also work well for S8, S9 and...

Why not simply carefully read my post? And also why do you ignore that within an updater-script the built-in mount and delete_recursive functions have to be used, instead of run_program - what indeed serves a complete other purpose?
Again:
Mount
This built-in command mounts a partition, so if you want to operate on files within system and/or data partition you have to mount system partition, data for data partition with this built-in function.
To mount system :
mount(“ext4″, “EMMC”, “/dev/block/mmcblk0p5″, “/system”);
Here mmcblk0p5 is the name of system partition for mtk 6589 chipsets (this name varies from device to device)
To mount data:
mount(“ext4″, “EMMC”, “/dev/block/mmcblk0p7″, “/data”); (partition name varies from device to device)
Take the time and look inside here.

Only to have said it: The updater-script, which is offered with the link - what also circulates under different names on the internet - is crap: the author(s) have no idea how to write a updater-script.

---

@Marvino.
Code:
delete_recursive("/system/app/BookmarkProvider");
delete_recursive("/system/app/Browser");
delete_recursive("/system/app/FaceUnlockService-res");
delete_recursive("/system/app/NfcNci");

Well, it might have worked in his device okay. Busybox mount use fstab in /etc. Not normally there in TWRP. So one should use device path as well.
The hardiest part I guess is to select what to remove really. What might work for some, might make a nice little sushi tray for another...

Have never understood it why people use true EDIFY conformant synthax when creating an OTA package: An OTA script can get realized as plain shell script - what makes things drastically easier and device independent.
BTW: All EDIFY functions can get replaced by equivalent user-written functions. See also here,
