Considering that we all will need to perform this joyous process when we least expect it and have the least time to do it. Would it be possible to bulletpoint the process to serve as a reference?
One thing I have noticed with some of the more recent versions of OS X (10.9 I think) is that once upgraded, HFS will no longer recognize volumes from previous incarnations of the Mac OS. This caused great panic on my end since it was unexpected, but it is important to note if you are trying to install a prior OS to a volume where the format or partition or whatever is not recognized by the HFS version of the OS you are trying to install. Just a nice detail. To mitigate this pain, I keep several VMWare Fusion VMs around at 40 GB a piece and when a new OS comes out, I duplicate the latest one, upgrade it, install Xcode on it and move forward. This way, I can always spoil up an older OS with a working version of Xcode on it if needed. Keeping these on a cheap and large HD and moving the one needed to an SSD is a cost efficient manner of keeping working older OSes with functional Xcode installs around if needed. Hope this helps anyone who might have to go through Graham's lovely ordeal.
