[Xen-devel] [PATCH 3/3] libxl: make the top level 'device' node in xenstore writable...

[Paul Durrant <pdurrant@amazon.com>]

... by the guest.

Since this node is created largely to host the frontend areas for PV
devices, all of which are fully guest-writable, there seems little point
in making the top level node read-only. Other toolstacks, such as xend,
did make the node writable by the guest and some PV drivers [1] relied
upon this to stash information.
