…as a rough way of knowing how many people successfully installed Tails (possibly first time users) and tried to reboot it

This implies replacing ‘#’ by ‘?’. Otherwise we won’t see this in the server logs.

Hint: starting with Tor Browser 8.0 — included in Tails 3.9 — the User-Agent correctly reflects the platform aka. OS being used.
