How large was your /usr/local folder before upgrading? Mine is currently at 12GB and I wonder whether I should try to reduce it even more.

It's really about the number of files, not the size involved. If you have hundreds of thousands of files in there, you'll have a long wait.

Just a warning - after 6+ hours (not sure exactly as I went to sleep) my Yosemite install failed because the log buffer was full. I can't say for sure that this would not have happened if I hadn't left the log viewer open, but I would recommend closing the log window when you're not actively using it.

I had 32k files using up 8GB in /usr/local, and the time spent on "2 minutes remaining" was about 45 minutes. In retrospect, I'm happy that I didn't waste any time on special preparations. One thing I learned is that the ⌘L log window blocks progression from restore to the next reboot; I lost about 15 minutes that way.

It seems you really must move it to ~/local or similar as the article points out. Moving to /usr/local.bak seems to still copy the files one by one into recovered items during the last stage of the installation.

What could possibly be driving this process though? What is the update actually trying to accomplish?

Not sure why the article hasn't considered this, but after moving /usr/local to another location and doing the Yosemite upgrade... you can always move the newly created Yosemite files/directories in /usr/local to your old local, rather than deleting them.

I've re-written the instructions a few times since I first posted it. Once it gets into conflicts and problems I can't cover everything, and I don't want to give a dozen commands for people to paste in and run for various scenarios and then screw people up more. I'll add a note to merge instead of replace, though, thanks!

I'll add that note. People with problems tended have >100k or more files.

All add a note about the log buffer, thanks.
