Does iPhoto really require Mac OS Extended (Journaled) Filesystem?
I have been looking for a way to conveniently share my iPhoto library between the three computers in my house. NAS seems like the right solution, except for this pesky requirement that iPhoto supposedly requires that the library reside on a filesystem with the Mac OS Extended (journaled) format.
I have seen this requirement referred to in several discussion threads, and in articles online, but I haven't found the source of this requirement. The iLife '11 system requirements article in the knowledge base (http://support.apple.com/kb/HT4163) doesn't say anything about filesystem format. And, I have seen a few notes by people who have been running for months with their iPhoto library on a NAS drive (which would be ext3 or ext4 format by default, accessed via AFP).
I have searched through the knowledge base, looked through the online help, and so on. I can't find any official source for this requirement.
Can anybody point me to an official source (support article, forum response by an Apple employee, etc) where this requirement is stated?
MacBook Pro, Mac OS X (10.6.1)
