Is there a need of new filesystem ? I am wondering why can't these be 
exposed via sysfs / securityfs ?
Probably, something like... /sys/firmware/secureboot or 
/sys/kernel/security/secureboot/  ?

Also, it sounds like this is needed only for secure firmware variables 
and does not include
other firmware variables which are not security relevant ? Is that 
correct understanding ?
