## TPM1.X back-end configuration

### TPM selection

The tzpfms suite connects to a local tcsd(8) process (at `localhost:30003`) by default.
Use the environment variable `TZPFMS_TPM1X` to specify a remote TCS hostname.

The TrouSerS tcsd(8) daemon will try `/dev/tpm0`, then `/udev/tpm0`, then `/dev/tpm`;
by occupying one of the earlier ones with, for example, shell redirection, a later one can be selected.
