You're right...

I have one more question. What are the drawbacks of not preserving Tor 
state directory between reboots? I reboot the router rarely, but it can 
happen from time to time. I run Tor from ramdisk and I don't want it to 
have any persistent storage - I want it to vanish completely as the router 
shuts down.

One drawback that I see is that after every reboot, a new entry guard will 
be selected and it can make correlation attacks easier. Maybe it would be 
wise to copy old state file during each "Tor deployment" process (by which 
I mean creating the ramdisk and copying Tor over the network to it from a 
secure machine)?
