		       TPM Management -	tpm_setownable

NAME
       tpm_setownable -	change whether the TPM allows tpm_takeownership	opera-
       tions

SYNOPSIS
       tpm_setownable [OPTION]

DESCRIPTION
       tpm_setownable reports the status of the	TPM's flags regarding if the
       TPM can be owned.  This is the default behavior and also	accessible via
       the --status option. Requesting a report	of this	status prompts for the
       owner password.	The --allow option sets	the system's TPM to allow
       tpm_takeownership operations (via the TPM_SetOwnerInstall API).	This
       operation requires physical presence.  The --prevent option (via	the
       TPM_SetOwnerInstall API)	prevents the TPM from accepting
       tpm_takeownership operations.  This operation requires physical
       presence.  These	operations are persistent.  tpm_takeownership requires
       the tpm be enabled.

       -v, --version

       -l, --log [none|error|info|debug]

	      Report the status	of flags regarding if the TPM can be owned.

       -a, --allow
	      Allow tpm_takeownership operations.

       -p, --prevent
	      Prevent tpm_takeownership	operations.

       -z, --well-known
	      Authenticate using 20 bytes of zeros as owner password (the
	      default TSS Well Known Secret), instead of prompting for an
	      owner password.
