Played around with installing it on the host (scale, vm).  It caused an issue with K3s if I started it on boot (haven’t done any troubleshooting), but worked if started later.  It worked otherwise.

These instructions worked for me. https://www.truenas.com/community/threads/howto-install-tailscale-in-a-jail.98910/

Has anyone set up tailscale on their TrueNAS. (I have a Mini X+) to access it from outside their home network? If so, does anyone have any advice? It seems like you could go a bunch of ways: 1) log in as root and install it on the host OS 2) use a virtual machine 3) maybe there are plugins?

Does anyone have thoughts/experience?
