So everybody is talking about a cool new Windows 8 feature called ‘Push Button Reset’. It will reset settings in Windows 8 to day #1. You can do the same with Linux / Unix, just run the command given below:
Warning: Do not run the following command on prods as upon executing this will halt your system and reset all basic settings.
At boot you need to change the root password, set new network configuration, time config, keyboard config, auth config (like use ldap or pam etc), and services config. Like Windows 8 IE/MSoffice, it will not modify Linux apps settings. Personally, I prefer editing individual files.
This is not a new feature as Windows 8 fan boys are claiming to be and it’s been around for ages. My best guess is that MS-Windows 8 users are going to use this feature frequently :P
Note: I’ve tested sys-unconfig on Solaris and RHEL. I’m not sure about Ubuntu but debconf provides similar features.
