Is there no way to force the nvram update without rebooting?
Anybody know if the kernel hooks in the IOKit for the NVRAM allow
for the creation of such a program?
Is the NVRAM memory mapped into the kernel such that the bsd kvm_read/kvm_write
calls can be used to update the NVRAM?
It makes for difficult cluster management if you have to reboot the
nodes just to udpate the nvram variables
