[Libguestfs] [PATCH] Enable autosync by default.

By a very strict reading, this is an API change. Matt argues (and I agree) that if you really depend on autosync being off by default, then you were depending on the undefined behaviour that happens when you kill the qemu container without first doing sync. ie. Data might or might not have been written, depending on how fast the kernel was writing to disk versus how soon the container got killed. On the other hand, this is a frequent cause of problems when using the API (see http://libguestfs.org/guestfs.3.html#libguestfs_gotchas) and changing the default means this problem goes away. You can revert to the old behaviour by adding: guestfs_set_autosync (g, 0); Rich. -- Richard Jones, Virtualization Group, Red Hat http://people.redhat.com/~rjones libguestfs lets you edit virtual machines.
