From these docs. it's not clear which values get mapped to which grub entries. One set 'appends', one set 'replaces'. Are they exclusive of one another? And, what specifically gets mapped to Xen kernel's "options=" parameter line? E.g., a grub2-mkconfig-generated xen*.cfg takes the form # disclaimer [global] #default= [config.1] options= dom0_mem= ... kernel=vmlinuz-4.3.0-16.gff1dcd9-xen ... ramdisk=initrd-4.3.0-16.gff1dcd9-xen ... whereas for a NON-xen grub*.cfg # disclaimer [global] #default= [config.1] kernel=vmlinuz-4.3.0-16.gff1dcd9-default ... ramdisk=initrd-4.3.0-16.gff1dcd9-default ... there's NO "options=..." line. The docs should clearly address which PARAMETERS map to the "options=" line, and which to the kernel=" line in the Xen case. To get there -- What's intended, by designn, from development in these specific *XEN* cases?
