Re: [Xen-devel] [PATCH] /sys/hypervisor/uuid

If we allowed unprivileged read access to xenstore, that would require
only a smaller and more general patch to the kernel. Then you could put
the uuid extraction logic in user space?

But if you still require xs transactions, then it remains complicated
and a potential way to introduce fun problems for dom0 from a domU.
Especially as I would expect that then people will start coding their
own stuff instead of bringing a dep on libxs into domUs

Well, the bottom line is: I will apply the uuid patch for sysfs if you want it. But don't be surprised if the whole lot goes in the bin at some point when we have the inevitable fight with the kernel maintainers. In contrast, libxs presents a stable supported interface.
