Should be decided per power cycle. I'm throwing one incomplete idea not all things considered... So one idea is would be to apply set operation to /dev/tpm0 as ioctl (would not be available for /dev/tpmrm0). Then at least access control rules would apply. The open here is that the IMA etc. will use a different locality during boot-time, like it would also with sysfs attribute. BR, Jarkko
