Tailscale asked me the password for my Encrypted HDD

Tailscale version: 1.32.2
Your operating system & version: Ubuntu Server LTS 20.04
I updated Tailscale on my linux server from 1.32.1 to 1.32.2. Before the updating procedure ended, I was asked for the passphrase for my encrypted HDD.
Is that normale? Why should Tailscale bother for that?
