I use Mandrake 9.1 very successfully and I noticed in our local online Linux store a disk containing "Mandrake 9.1 GPL Updates" so i ordered it.
It has since arrived and it has three directories on it (RPMS, SRPMS, base) which are full of rpm files.
Being a newcomer to Linux I'm not too sure what should be done here. How do I know what to update, or do I update 'everything' and how much damage am I likely to do if I do this?
