On Proxmox, as much as possible I would just spin up an Alpine or Debian LXC container and install whichever packages I need, so it is more manual than the Jail-based plugins, but not a huge inconvenience. While typing that I remembered another annoyance I had with TrueNAS, which is that it doesn't let me pick truly custom MAC addresses for my Jails or VMs, which I like for DHCP reservations. I use Coca-Cola's prefix, because it's funny and I know immediately that it's one of my hosted services. I recall a blog post or thread somewhere describing the issues TrueNAS devs had with Jail plugins, but can't immediately find it again. If I do, I'll link it.
