Is this issue not analogous to "I made changes on my z/OS system, and now some critical software product is broken?"
In that case, you would use SMP/E or volume backups to go back. Isn't linux essentially the same (only different)? For my Linux desktop (Ubuntu), with the package manager (synaptic / apt) it is pretty easy to roll back changes (like a kernel version). I also keep an unmounted mirror disk for my OS disk and use a cron job to rsych to it automatically on the weekend. Rolling back the entire OS volume takes about 5 minutes using rsync (after booting from a thumb drive). ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
