However, most non-ancient 4.x loaders can : boot a 5.x kernel sufficiently well that this shouldn't be a crisis. Or, : they used to be able to when I last tried it (not too long ago). The big issue is (or at least used to be) device.hints. However, I see in the Japanese mailing lists they recommend using the 4.x /boot/loader, interrupting the boot process, typing 'unload' and then 'load /boot/kernel/kernel' followed by 'boot'. It generally will work, but some machines with ACPI might have issues relating to interrupt routing (a number of newer machines are known to work with ACPI interrupt routing, but not PCI BIOS). It seemed safer to recommend installing a new /boot/loader. Warner To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
