I find this all very interesting...

"Please keep in mind the current 0.5.2 stable release does not yet
support a mountable filesystem. This functionality is currently
available only in the 0.6.0-rc6 release candidate."

"Uploaded October 14, 2011"

So in the past ~two weeks, you converted your 15K+ user production

misinterpreting the date given that 0.6.0-rc6 was released?
