Well, for all my other servers, I standardized on ext4.
Since a vFirewall have to perform lots of packet-juggling, I'd rather
dedicate the CPU time to the kernel rather than the HD I/O.
Of course, a vFirewall needs to be updated every now and then, but
everytime an update is called for, it should not overly tax the CPU
and degrade the netfilter framework.
