6 RPMB frames can be routed to the RPMB device via the
7 user-space daemon tee-supplicant or the RPMB subsystem
8 in the kernel. The value "user" means that the driver
9 will route the RPMB frames via user space. Conversely,
10 "kernel" means that the frames are routed via the RPMB
11 subsystem without assistance from tee-supplicant. It
12 should be assumed that RPMB frames are routed via user
13 space if the variable is absent. The primary purpose
14 of this variable is to let systemd know whether
15 tee-supplicant is needed in the early boot with initramfs.
