Just comparing an operating system with all kinds of software and a kernel
that supports just about anything vs a stripped down o/s designed

simultaneously.  Just my 2 cents worth & my personal opinion based on past
experience.  I've been running PIX firewalls since 95 and never had one
crash even once.
