Testing in a VM might be helpful and can yield very different results, so it doesn't give you anything more than an indication. Besides, I don't find it easy at all to set one up because the networking part is extremely difficult. Even with that solved, how would I clone the system that needs to be upgraded 1:1 into a VM? I don't even have the disk space for that. > critical servers are generally on vortualization here > and in this case cloning even the production system > is easy > > hence in context of my phyiscal workstation there is > one at the office and one at home with are both > 100% clones by start both with a live-cd and mirror > the four RAID10 disks with dd/ssh to the second one > > the same works by pull 2 of the 4 RAID disks and put > them in the other machine, if it refuses to boot because > of too few disks to bring up the mirror a) you pulled > the wrong one and b) there is no change on disk, simply > put one back and take a different disk to the new syste, You're really going to extreme lengths to be able to upgrade Fedora. Do you seriously think all users need to run their systems in VMs and have two (mostly) identical computers around so they can upgrade? I guess not everybody wants this, and not everybody has the means to do this. >> Well, I can only follow the upgrade instructions.

It's good for you to stick with something inherently unreliable and unpredictable because otherwise you might lose your job. It's bad for me because I would only be wasting my time and money, and I might lose my data. Your conclusion would have to be that Fedora can only reasonably be used in a professional environment like you have at your disposal and that it is totally unsuited for what they say that their user base is. -- "Object-oriented programming languages aren't completely convinced that you should be allowed to do anything with functions." http://www.joelonsoftware.com/items/2006/08/01.html -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
