+1 This is a feature (kernel update) that is used by everyone, including newbs. They don't have to understand anything to enjoy the update, and they shouldn't have to understand anything to avoid the space filling issue. Lots of ways to fix it, I don't claim to know which is best: * Always leave N% /boot available, and delete or move old kernels to satisfy that. * Move old kernels to /old_kernels, outside of /boot. Driven either by satisfying N% space, or no more than K number of kernels kept in /boot. * Opt in, opt out, ask this on installation and for non-server installs, default to "never have to think about this again." * Easily configurable in the "whatever that box was called when I last used Ubuntu years ago" box.
