That's exactly what the floppy- and cd-rom based solutions do. In fact, the
amount of RAM needn't even be all that large, although more is always a good
thing.

The appeal was putting it into a notebook with no hard drive to reduce power
consumption, noise and heat in a small form factor, while providing a nice
built-in UPS. I simply don't want any more tower cases.

As Craig pointed out, the truly paranoid are already sending all logs to a
centralized location anyhow, so that's not a problem. Having syslog do both
local and remote logging is straightforward.

Well that's another idea I've toyed with: One of those $40
boot-from-compact-flash adapters that emulate an IDE drive. Note sure about
stuffing one into a notebook case though.
