kexec-tools

tools to support fast kexec reboots

This package provides tools to load a kernel into memory and then "reboot" directly into that kernel using the kexec system call, bypassing the normal boot process.

molly-guard

protects machines from accidental shutdowns/reboots

The package installs a shell script that overrides the existing shutdown/reboot/halt/poweroff/coldreboot/pm-hibernate/pm-suspend* commands and first runs a set of scripts, which all have to exit successfully, before molly-guard invokes the real command. One of the scripts checks for existing SSH sessions. If any of the four commands are called interactively over an SSH session, the shell script prompts you to enter the name of the host you wish to shut down. This should adequately prevent you from accidental shutdowns and reboots. molly-guard diverts the real binaries to /lib/molly-guard/. You can bypass molly-guard by running those binaries directly.
