The Xen wiki uses: "pv-grub" in: http://wiki.xen.org/wiki/Xen_Common_Problems http://wiki.xen.org/wiki/Xen_FAQ_Design_and_in_Depth http://wiki.xen.org/wiki/Xen_PCI_Passthrough http://wiki.xen.org/wiki/XenUsersQuestions http://wiki.xen.org/wiki/Xen_Beginners_Guide "PV-GRUB" in: http://wiki.xen.org/wiki/PvGrub http://wiki.xen.org/wiki/PVGrub_HowTo "PvGRUB" in the title of: http://wiki.xen.org/wiki/PvGrub http://wiki.xen.org/wiki/PVGrub_HowTo It is fairly obvious that /usr/lib/xen/boot/pv-grub-x86_32.gz in http://wiki.xen.org/wiki/PVGrub_HowTo is correct, because it specifies a file name where the convention is all lower case. I''d like to standardize the others as PV-GRUB, even changing the copies in the Xen wiki of questions submitted to the mailing list, so it is easily recognized we are referring to a certain component of Xen.
