   Be a bit carefull with tempfs. Because it resides in memory (at   
   least, on solaris it does).   
   Normally /var/tmp isn't really used, except when you have temporary   
   files that you want to keep over reboots. Normally /tmp is tempfs and is   
   used for the really temporary files. They will be unavailable after a   
   reboot, because tempfs resides in memory (or IIRC on swap even), which   
   is lost with every reboot.   
      
   Like stated earlier, the /var filesystem is suffered to have lots of   
   writs to it, because of the logs. Therefore it needs to be read-write.   
   You also want to have write access to /home. You want to have write   
   permission to, let's say .bash_history or .history, but also maybe your   
   .ssh/known_hosts. Making it ro, it will be very hard to do normal user   
   stuff on the machine. It depends on the purpose of your system, but   
   making the /home ro will make it quite difficult to do normal user stuff   
   on it.
