I am using LineageOS 18.1

When I was on LOS 16, I used to edit the file /system/etc/init.d/00banner and put my iptables commands there, e.g.:

#!/system/bin/sh
sh -c 'iptables -A OUTPUT -m owner --uid-owner 10195 -d 203.205.255.78/23 -j REJECT'

All iptables commands I put in there used to run on phone start up. But in LOS 18.1, the /system/etc/init.d/ directory was deprecated.

1. I created and filled the custom script with the iptables commands above:

touch /system/etc/custominit.sh
chmod 0755 /system/etc/custominit.sh

2. Then I edited /system/etc/init/hw/init.rc and I added to the end:

chmod 0755 /system/etc/custominit
exec /system/etc/custominit

3. I also tried adding:

service custominit /system/bin/custominit.sh
    disabled
    oneshot

But none of this worked.

What is it that I doing wrong? I have root access but I do not want to install any additional apps on my phone for this, as it was possible to do on LOS 16.

Issue was solved by following instructions here:

https://ch1p.io/lineageos-run-shell-script-at-boot-as-root/

The main issue turned out to be missing full path of executables, e.g.:

/system/bin/iptables instead of iptables

Once you added your service as "disabled" on init.rc you must call it on boot, add the following lines:

on boot
    custominit your_params

I hope it solves your problem
