Re: [Xen-devel] use case for exposing xenstore attributes via sysfs [lon

It would also solve the general problem too. There's a really
interesting article on LWN right now about sysfs being part of the
Linux userspace ABI. If we expose parts of XenStore that aren't
frozen (all of the Xend stuff which includes UUID isn't frozen) via
sysfs then it would be wrong to ever change those things.
I think you could write up a pretty simple module that provided this
for domUs. Would having a simpler kernel interface for XenBus be
acceptable? We could just change xenstore-* to use that interface
and get rid of xenstore_domain_open() (is anyone actually using this
interface anywhere else?).
It gets harder if anyone wants to construct transactions or register
watches from user space. We could support both interfaces though
(simple restricted, and complex flexible).
