I always do as Nio said, a */home* separated partition, then you can make as many installations you want on your *root* partition without loosing anything important. User configurations will be stored on */home*.
On this case (fresh install to* /*), you need to reinstall aditional software. But that is quite small compared to a full installation upgrade. To separate */home* from */* on installation, you need to use the "manual option". I guess there is tons of tutorials about this on the net... 2014-07-23 8:24 GMT-03:00 Nio Wiklund <[email protected]>: > Hi Basil, > [I will reply inline] > Best regards/Nio > > Den 2014-07-23 13:08, Basil Fernie skrev: > > Hi Nio, > > > > Thanks for the prompt response.
