The old xenstore userspace tools expect to find "xenbus"
under /proc/xen, but "xenbus" is now found at the root of the
xenfs filesystem. Selecting this causes the kernel to create
- the compatibilty mount point /proc/xen if it is running on
+ the compatibility mount point /proc/xen if it is running on
a xen platform.
If in doubt, say yes.
