As you suspected, security isn't much of a problem here. I do recommend
moving the gateway to a system not running other services. It has nothing
to do with security, but rather with performance. Given the gratuitous
interrupt junkies that typical 'home systems' are, you will find it
increasingly difficult to maintain minimal connection latency as usage of
the other services (especially NFS) increases.

Except for decent password management, keeping an eye on security updates,
and a detection system for basic intrustions, AFAIK not much can be done
in a home contect.

Paranoia ain't cool. I don't mess with any of those anymore for that exact
reason -- it /makes/ you paranoid. I used to make everything under /usr
ro, but it' just a pain in the end while offering very little to no extra

Argh, never run unstable releases on a server so versatile. Please. It's
just /begging/ for trouble.

From the fool file:
I don't see why the way people have historically partitioned disks should
dictate which kernels we build and distribute by default in the future.
