Just tried this out and had a partial success. On Ubuntu 18.04 and a Ravpower WD09.

Firmware 2.000.008

About the RoboFile.php:

The chroot command kept failing for me. Had to change the following line:

-        $this->_copy('/usr/bin/qemu-mipsel-static','build/usr/bin/qemu-mipsel');
+        $this->_copy('/usr/bin/qemu-mipsel-static','build/usr/bin/qemu-mipsel-static');

I do not have robo.phar installed in /usr/local/bin. Would have been nicer to wget it in the script.

Apparently my device does not support ext4 (missing in /proc/filesystems). So changed it to ext2:

-        $this->_exec("mkfs.ext4 ./output/extern_package");
+        $this->_exec("mkfs.ext2 ./output/extern_package");

About the WD09 device:

The rc.local script on the device does not seem to work. It tries to mount to /extern but that directory does not exist. I changed it to /mnt and updated the init scripts.

Dropbear is started correctly but I could not login as root because the default home dir /root does exist. Also changing the root password requires manual merging of /etc/passwd and /etc/shadow. And perhaps login as root should be disabled :-)
It would be nice if startup.sh also added /opt/bin to the PATH.

Lastly I wanted to add a swap file but the swapon function always fails with 'Function not implemented'. It seems the kernel is build without support for this :-(

Hey!

Following your PHP script, I've created an installer package that does the same, without the need of a PHP runner, or a separate server with qemu, but rather, right on the FileHub.

The script set is available here. As you can see, it follows your script step by step:

1. Creates a temporary EXT2 chroot image for Entware to run the install in
2. Mounts tempFS to $(pwd)/build
3. Creates minimal viable file system for chroot, adds busybox and symlinks, mounts /dev and /proc
4. Chroot's into $(pwd)/build, retrieves Entware install script, and runs it
5. Installs busybox, entware-opt and dropbear packages
6. Creates final extern_image, a 128MB EXT2 image, and mounts it to $(pwd)/entware
7. Copies the $(pwd)/build/opt folder to $(pwd)/entware
8. Destroys the original chroot and unmounts the images, cleaning up the remains
9. Copies an updated rc.local to /etc, and runs etc_tools p to persist this change

The image is created properly, and for some mysterious reasons, my firmware (2.000.018) came with /opt existing, but /extern does not - which is why the rc.local changes are necessary. I also took some liberty to make the script itself a bit more dynamic.

This new rc.local runs fine on boot, however... When it is executed, the /data/*DiskN mounts do not exist yet, meaning it never succeeds on its own to mount these.

As you've previously managed to get it working, would you mind giving a few pointers on how to get this mount to work? I thought about adding some repeat retries to the script (try in first few minutes of boot), or possibly patching the script responsible for mounting the disk partitions.
