Upgrading from 4.0 to 4.6

[Moltke]

It'd be nice if one day Linux can do this - create restore points - without needing additional software and without user intervention, something like Windows' VSS  - volume shadow  copy service - I do remember reading once about some guy's project related to this, can't find it now though. I know  cron can offer a similar approach, but then users have to know what to do and I guess it's ok, I myself use it but those who just arrived at Linux won't have a clue and frankly, it's just not the same. I think that would be a massive improvement for Linux in general. Just my 2 cents.
