Public bug reported: I'm using a VM, running 12.10, upgraded from 12.04.1 (server). Using a bzr checkout dir on the VM and mounting that locally on the host with SSH from /home/USER/.gvfs/home/VMUSER/work/maas, symlinked to /home/USER/work/maas, then running bzr branch --switch on the host, while in the symlink dir. I get an Error 95 Operation not supported. And looking at the traceback in the log, it seems the fs reports erroneously supporting fdatasync, but actually fails later when bzr tries to do it.
Running the same command on the VM locally works.
