Plus the fact that being a Red Hat clone makes it easier to find people with appropriate skills. These systems will be minimal installs - even less than the default minimal that can be achieved via Anaconda, plus a couple custom packages. Think - home-made appliances, or sorts. There will be very, very few things running on these machines. The problem with kernel 2.6.18 is that netfilter has the old (I mean, current) braindead conntrack that is loaded when NAT is used. Now, configure pktgen full blast over a gigabit link, small UDP packets, set it to generate random source IPs (DDoS simulation) and point it to a Linux router with conntrack loaded, and you'll see why I can't use the default kernel. Apparently there will be improvements in that regard in 2.6.23, and I've heard that 2.6.24 will actually be able to do 1:1 NAT without conntrack. -- Florin Andrei http://florin.myip.org/
