Unable to use Installer Script in TrueNAS latest version

[cgtechuk]

Hi there, trying to get up and running but I am hitting an issue where the install script run on a Truenas VM on Proxmox with HBA and drives passed through is getting an error when trying to install.

I have tried running it as truenas_admin and root same error, Command being run is:

root@truenas:/mnt/nas/home# curl -sSL https://raw.githubusercontent.com/DAB-LABS/smart-sniffer/main/install.sh | sudo bash
The error I get is:

`
╔══════════════════════════════════════════╗
║ SMART Sniffer Agent — Installer ║
╚══════════════════════════════════════════╝

--> Detected platform: linux/amd64
✗ No writable install location found. Tried /usr/local/bin, /DATA/smartha-agent, /opt/smartha-agent.
`

Expected behavior
App did not install, doesnt respond on the port mentioned so assume its not actually installed itself. I have never used it with TrueNAS before I cant comment on whether its a recent TrueNAS incompatibility issue but I do know that they lock down their file systems and make them readonly. Really appreciate your help with this as app is just what I am looking for

Smartctl works perfectly and I can see all SMART data as expected from TrueNAS VM , Scrutiny is working too but I would like to be able to get a more lightweight interface purely just for monitoring temperatues
