[BUG] Boot sequence, IPFS before custom-cont-init.d

[hulkhaugen]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

I'm trying to add a custom script to this container, but I'm facing some challenges. I'm very limited in this field, but it seems to me that the script(s) in custom-cont-init.d are ran after some IPFS related stuff. The issue for me personally is that I want to remove /data and make a symlink from a variable, let's say /share/emulatorjs to /data. I'm doing this for a Home Assistant Add-on, so I'm somewhat limited from the usual approaches.

Maybe i'm approaching this wrong, I just want to be able to move the roms folders to /share.

Expected Behavior

Run script before anything else inside the container

Steps To Reproduce

• Fresh install 1.7.3-ls75
• Make a script that deletes /data, and adds a symlink from /share/emulatorjs to /data
• Include the script in custom-cont-init.d
• What the logs that says: cannot remove 'data': Resource busy

Environment

- OS: HassOS
- How docker service was installed: Plain, only added said script

CPU architecture

arm64

Docker creation

ARG BUILD_VERSION
FROM lscr.io/linuxserver/emulatorjs:$BUILD_VERSION
# Add custom script
COPY rootfs / 

********************
* custom-script.sh *
********************

#!/bin/sh

# Read the target folder from /data/options.json
# Default value is /share/emulatorjs
TARGET_FOLDER=$(jq -r '.rom_folder' /data/options.json)

# Ensure the target folder is owned by root
mkdir -p "$TARGET_FOLDER"
chown root:root "$TARGET_FOLDER"

# Create a symlink from /data to the specified target folder
rm -rf /data
ln -s "$TARGET_FOLDER" /data

# Debugging: Print the current state
ls -la /data/

If you want things to run before certain init scripts, then you'll have to inject proper s6 init steps. Take a look at this mod for instance, where it injects two separate init steps into different spots, one before package install and one after: https://github.com/linuxserver/docker-mods/tree/code-server-flutter
