I want to do exactly that -- shift a machine running SL (whose list is not on Gmane, oddly) to CentOS, if possible without losing my tweaks nor my data. But I'm confused. Your advice : I would strongly suggest something akin to yum reinstall \* and leave it to chug away (backups first naturally) for a while to refresh all the packages and teh rpm database to be in sync with the centos build..... requires matching, same build options for sure etc etc.... is Geek to me.what is "\*"? What rpm database? The one on my machine? What's in the repos? Or ....? What are build options? (I don't do things like make and install, because I'm not competent to recover from bloopers -- and I have a sneakin' hunch build is among those things.) What does etc., etc. include? Might there be a web site somewhere with a pons asinorum for the subtechnoid? -- Beartooth Staffwright, Not Quite Clueless Power User I have precious (very precious!) little idea where up is.
