Why SBIN? Is there anything wrong with allowing unprivileged
users r/o access? Or is this because in order to access the
hypercall interface one needs to be root? If so, we may want
to consider relaxing/avoiding/bypassing this in some sensible
way.
Installing to bin is fine with me, but relaxing the root restriction
might be more difficult and/or questionable.
I was thinking of "mounting" the xen-sysfs to either Xenstore or
the kernel's sysfs (probably the latter, as Xenstore in a stubdom
would need to enable access to xen-sysfs for that stubdom ,too).
This would then enable accessing some or all entries from non-root.
