Try doing that with the kernel. Last I looked, Tomato's optware
repository doesn't include kernels.

OpenWRT's optware repository does have kernels but they're covered in
caveats that you're likely to brick your device if you try to install
them. The supported kernel update method for OpenWRT is Sysupgrade which
erases what is there and flashes a pristine system image. Just like I

So yeah, I stand by my notion of how embedded systems work. Empirically,
that's how they work.

I've deployed and managed a few enterprise grade firewall appliances
like Borderware and Firewall-1. This is not a feature typically found on
such devices. Borderware, at the time running on FreeBSD, required a
restart in single-user mode to perform major changes because the root
file system was normally mounted read-only. Firewall-1 varies with the
foundation: IPSO, Solaris and Windows/NT all behave differently.

I can't recall seeing a consumer grade gateway with a feature like this.
Not a physical switch, anyway.
