[SOLVED] Reading config.xml From cd1 Using opnsense-importer

[utkonos]

Greetings,

I am attempting to load a configuration file from a mounted ISO rather than a USB. The use case is for deployment on a VM inside of Proxmox, a virtualization environment. Generating an ISO and then uploading it to Proxmox's ISO storage is straightforward as is adding a second cd drive to the VM with that ISO attached. The result is cd0 with the OPNsense ISO attached and conf.iso attached to cd1. The layout of the conf.iso is /conf/config.xml as outlined in this previous thread:

https://forum.opnsense.org/index.php?topic=22307.0

Both devices are recognized correctly during first boot. When I press any key to start the configuration importer, both are listed:

<QEMU QEMU DVD-ROM 2.5+> at scbus1 target 0 lun 0 (cd0,pass0)
<QEMU QEMU DVD-ROM 2.5+> at scbus1 target 1 lun 0 (cd1,pass1)

When I select "cd1" at the prompt as the device to import from, it doesn't find the configuration and the following is printed to console:

No known partition layout was found for 'cd1'.

Is there a change that I can make to the ISO image that will allow this to work?

It looks like the opnsense-importer is looking for a MBR or GPT partition table or a zfs pool, not a ISO 9660 filesystem ...

Yeah, we need to patch in ISO support but it could be done (similar to what msdosfs is doing) if you could raise a ticket on GitHub.
