We do very cross-platform development, so it's not strange to see boxes with Linux and 2 or 3 versions of Windows.
So far I have a SVN working copy of our projects in each platform, which becomes kludgy at times. I'm thinking of using a single partition for the projects, accessible from all platforms. Looks like the only option would be FAT32 or NTFS (which Linux, Windows and even Mac can read/write).
I'm a bit worried about different filesystem semantics, though. For example, case-sensitiveness, ownership and permissions.
Can you recommend a better portable filesystem? Do you think my objections are unjustified?
EDIT : Let me clarify. I love SVN. What I'm looking for is to have a single working copy in my local machine shared by all the OSes in it. Especially when I'm working remotely, I want to check out or update once and use the same working copy from all the OSes.
