Hello, we have several physical servers (CentOS 5.*) with rather critical applications where (because of stability) we don't do regularly 'yum update'. In virtualized environemnts (under Vmware) we do a snapshot, then 'yum update', reboot and if something is wrong we rollback the snapshot. On physical servers we cannot do that. I have read about rollback option of rpm but not sure if this is reliable solution. What is your best practise regarding "rollbacking" 'yum update' on physical servers ?
