Disabling all of the available boot options for the system doesn't prevent incidental breakage, it just changes the *kind* of incidental breakage you get. The *least* bad solution we have today is that some packages (lvm, udev) refuse in the preinst to continue being installed when upgrading from sarge (lvm for upgrades from either 2.4.27 or 2.6.8; udev from 2.6.8 only), and then the user is left to figure out how to get a viable 2.6.1x kernel package onto their system after a dist-upgrade has left God knows how many packages in an unconfigured or inconsistent state. Anything that introduces the possibility of the system breaking on reboot/power failure is *worse* than this. > - Refuse to start on startup if no compatible version is found. What does this mean, exactly? Should that be "upgrade" instead of "startup"? And how does that help us improve users' experience when upgrading? -- Steve Langasek Give me a lever long enough and a Free OS Debian Developer to set it on, and I can move the world. vorlon@debian.org http://www.debian.org/
