Automatic Geli?

[Fa bio]

Hi!



Is it possible to recompile geli/kernel to automatically enter with password and/or key? I´ll explain with an example:



If you see a cache system called SpeedR (http://www.speedr.com.br/?locale=en), in their site you can download the ISO and burn it to a CD (http://www.speedr.com.br/rc/speedr-0...rc18.2-x64.iso)



It´s very interesting, because all partitions are encrypted with Geli, 
but there is no passphrase to enter at boot time or key directions in loader.conf file.



If you mount the partition with another FreeBSD you see only /boot dir. All files are secure!



At boot time you can see this:

Timecounters tick every 1.000 msec
ipfw2 initialized, divert enabled, nat enabled, rule-based forwarding enabled, default to accept, logging disabled
load_dn_sched dn_sched FIFO loaded
load_dn_sched dn_sched PRIO loaded
load_dn_sched dn_sched QFQ loaded
load_dn_sched dn_sched RR loaded
load_dn_sched dn_sched WF2Q+ loaded

How is it possible?



Important: I don't want to get inside this system! I just want to 
understand how it is possible to automatically mount geli partitions 
without entering any key or passphrase.



I saw many tutorials but they all ask to enter a passphrase!



Any ideas?



Thanks

Felix
