Graham, This is exactly the strategy that Avaya uses in it's enterprise pbx platforms. They maintain two separate partitions for the PBX apps. When an upgrade occurs, they upgrade the offline partition and then switch to it. If the upgrade goes badly, they reboot and they're back on the old partition like nothing happened. If it goes well, you have to run a command that switches the bootable partition in lilo. Here's a partial screenshot from their web interface:
Partition Status Physical Software Boot Active Partition Release Partition Partition hda1 01.0.628.0 no no hda6 01.0.628.3 yes yes This strategy has saved us a lot of work on one occasion when we shot ourselves in the foot. We rarely ever worry about the upgrade process with this to fall back on. On 2/7/06, Nguyen <[EMAIL PROTECTED]> wrote: > That looks cool.
