I noticed your are using unionfs. Is it working without any problems? 
Every time (in the past) I read that somebody tried it, it always has 
some problems with stability etc.

And what you are using to update / upgrade modified system files in 
thinjail1? (if nullfs ro shared base is updated / upgraded)
