System Restore in ubuntu!

[HROAdmin26]

I could certainly see how this could be done - but it would require persistent filesystem snapshots. The obvious method would be LVM snapshots (although I am personally not an LVM fan.)

Something along the lines of:

> OS is running - snapshot is created (manually or automated.)
> Updates are applied and filesystem is changed.
> Upon normal reboot, OS doesn't boot.
> Reboot again - a GRUB option was previously added that boots a very basic kernel/shell. The shell gives a menu - here are the snapshots available - do you want to rollback to one? User selects a time before update and filesystem is reverted to snapshot.
> System reboots - now the normal GRUB option will boot successfully.

Hi guys!!
We have started the project "System Restore in Linux".
We need various scenarios from you where in
(i)you were not able to login due to deletion of particular files/directory.
(ii)you faced problem in ubuntu due to any updates installed manually/via update manager.
(iii)you faced problem with other cases you experimented with.

(SIMPLY TO PUT,LIST THE CASES THAT MADE YOU REINSTALL UBUNTU)
