I've just confirmed it. In plymouth, file src/ply-boot-server.c, I've
added the ply_trace line:
                        ply_buffer_append_bytes (buffer,
                                                 strlen (password) + 1);
                        ply_trace("Carles password: %s", password);

Then I can see in the Debug logs the previously entered passwords when systemd
requests them (which then systemd uses them to decypher the partition and add
the correct one in the Linux keyring, etc. etc.).

Thanks for all the help and checks,
