Possible issue with Entware mounting

[fonix232]

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.
