Or you can create a generic symlink like "vmlinuz" or "kernel" (and "vmlinux1" or "kernel1" for an older kernel, etc) to the kernels of the distros - in their own "/boot" directories - that don't control grub and point at them via "40_custom". -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://lists.fedoraproject.org/admin/lists/users@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
