Description: 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.
