Running low on diskspace
 

Is it safe to delete some files in the tmp folder and when reinstalling SuSE
is it possible to save the settings from the home folder to import all of the settings.

things in /tmp are up for deletion usually. normally best to drop down to a console (i.e. no X) and stop any available services just incase.

as for your home question... that's why you should have a seperate /home partition. that way you can format your root partition totally, but the old /home data won't be touched at all. if you do not have a seperate home, then i don't believe there's any nice way to help. just take a backup to CD or something beforehand. Most "upgrade" or "repair" instalations won't actually format anything, so you could well get a damaged system back up without a full reinstall.
