Libguestfs - May 2011 - rsync support

Hi Rich et al.,

Has an rsync addition to libguestfs been considered? It would be great to have
when copying the contents of a filesystem to a disk of a different filesystem.
It could also be used to keep portions of cloned machines in sync. For example,
I'm porting VirtualBox images to Xen. I sometimes make change to the source
image that I would like to easily propagate to the Xen copy. DD is sometimes a
bit too low-level.


Regards,
Chris

I think this makes sense.  As a matter of getting changes in
libguestfs it's better to propose patches and APIs.  You could test
this out by adding rsync to appliance/packagelist.in, and then adding
some APIs to libguestfs (see [0] and example [1]).  Post the patches
here and we can review them.

Rich.
