boot parameter
Hi, Is it possible to pass arbitrary parameters to boot(8), respectively the kernel, so that they can be read from the running system (in userland)? While poking in the boot(8) sourcecode I found the option env. Could somebody please tell me what this (undocumented, at least in the boot(8) manpage) option is used for? thanks, Robert

Re: GRUB's boot parameter - don't do it!!!!
I think using grub is shameful and insecure enough :) I would not rely on boot loader that resides outside of MBR. The best thing for multi-os pc is distro-independent loader (e.g. GAG) + partion loaders for each specific OS. Don't want my OpenBSD to depend on Linux partitions :) My personal opinion PS: grub still can be second level boot loader, e.g. for Linux affiliates. Be careful with GRUB on Linux partition if you are not yet convinced :) --- ikesan [EMAIL PROTECTED] wrote: On Thu, 16 Jun 2005 18:39:37 +0200 Matthias Kilian [EMAIL PROTECTED] wrote: On Fri, Jun 17, 2005 at 01:12:59AM +0900, ikesan wrote: root (hd2,0,a) kernel --type=netbsd /bsd Use the chainloader.

Be careful with GRUB on Linux partition if you are not yet convinced :) grub is bad, ugly, GNUish and it's a dead project since a while GRUB Legacy is no longer being developed. For the differences between GRUB Legacy and GRUB 2, please visit their respective pages. and there doesn't seem to be any progress in the grub 2 development... besides all the uglyness, i do like the flexibility and the network-booting capability of grub. i didn't find any similar replacement so i still use it in some scenarios. btw.: there are some patches for using grub with OpenBSD http://www.berger.to/openbsd/pxegrub.html. nevertheless, use the openbsd (pxe) bootloader or grub chainloading ;) reyk
GRUB's boot parameter
Hellow. I'm gonna boot OpenBSD from GRUB in FD. The parameter is following. root (hd2,0,a) kernel --type=netbsd /bsd But unfortunately panic occured. Message is following. panic: /boot too old: upgrade! This is first time that I installed OpenBSD in my PC (Athron CPU). And this PC contains some kind of OSs. So I usualy boot any OS from GRUB in FD. If version of OpenBSD 3.7 's boot parameter changed or parameter I set was wrong, please let me know correct thing. -- [EMAIL PROTECTED] -
Re: GRUB's boot parameter
This is probably because OpenBSD != NetBSD, and I suspect grub is using whatever it's notion of a netbsd boot block is. You probably have to fix grub somehow to use a current OpenBSD boot block, as opposed to attempting to start a kernel boot as if it were NetBSD. Ask them for a --type=openbsd option would be a start. -Bob * ikesan [EMAIL PROTECTED] [2005-06-16 10:23]: Hellow. I'm gonna boot OpenBSD from GRUB in FD.

speaking of GRUB: The most embarassing comment came from a developer of the GRUB project who went only by the name of 'Gord'. 'This function is truly horrid,' he wrote.

Re: GRUB's boot parameter
You don't get it. I said to ask the grub people for a correct openbsd boot option. The problem is grub is attempting to boot OpenBSD as if it were an old netbsd kernel. This will not work. You should ask the grub people to fix it. My advice? don't use grub. -Bob * ikesan [EMAIL PROTECTED] [2005-06-16 11:29]: On Thu, 16 Jun 2005 10:27:15 -0600 Bob Beck [EMAIL PROTECTED] wrote: This is probably because OpenBSD != NetBSD, and I suspect grub is using whatever it's notion of a netbsd boot block is.

Re: GRUB's boot parameter
Gag is the way to go, easy to use and even looks pretty. Subject: Re: GRUB's boot parameter GAG [1] is a nice boot manager. It can boot a lot of OS's, including OpenBSD. You should give it a try.
