I suspect NFS is working correctly, and my problem is simple file
permissions. User 1000,1000 (Alan) cannot modify these files on Linux
either. The ownership is root, the permissions owner:rwe, group:re,
other:re. I'm missing something basic - how do I get control of these files.
Bearing in mind that this is a FAT32 filesystem, so presumably doesn't have
permissions until it's mounted on Unix. Where do those default permissions
come from? Or am I (probably) misunderstanding something basic?
