Actually... it does. Thanks for pointing that out (forgot about that). The only thing that it doesn't do which I wish it did was fixup module_path. Right now if you break into the loader prompt and do 'boot foo', you end up with module_path containing "/boot/kernel;/boot/modules;/boot/foo". What I would like is to be able to use 'boot foo' and get a proper module_path. Yeah - I found this out the hard way when playing with incompatible versions of zfs.ko. I suppose the "boot kernel.old" method works if "kernel.old" is "close enough" to "kernel", as you'll get the kernel.old/kernel file, and kernel/zfs.ko kernel/opensolaris.ko modules loaded that way. -Kurt ___ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"

Nathan, Can you drop into your /boot/loader.conf: loader_delay=3 And reboot? I'm trying to think how we could use that to our advantage. I'm interested in creative applications thereof. For more skinny on what that does... "man delay.4th", it spills the beans on a "delayed command execution" module that I added a few years ago. For example... Here's my idea of making things easier on the user that wants to load a different kernel, but *without* using a menu... 1. We have loader_delay default to 3 2. Dots are displayed for 3 seconds before we do anything (like load a kernel) 3. User presses ENTER during those 3 seconds, and the delay is truncated 4. User presses Ctrl-C during those 3 seconds (or ESC) and they get a prompt (before the kernel has loaded). Then here's what I would do (as to not have to load separate modules)... set kernel=kernel.old boot + The forth code figures out that the kernel is in /boot + If loader.conf had opensolaris_load=YES and + zfs_load=YES then the forth code also loads those from kernel.old But let's say loader.conf was bare, you could do: set kernel=kernel.old set opensolaris_load=YES set zfs_load=YES boot NB: The reason this works is because you would not call "start" in your loader.rc (which actually loads things), but instead "initialize" (which only loads loader.conf et. al.) followed by dc_execute to fire off "autoboot" in 3 seconds (with the aforementioned allowed interrupt ability). Is that what you were thinking? Will that work? Bonus: It would be extremely trivial to implement. -- Devin _ The information contained in this message is proprietary and/or confidential.

For i386 and amd64, they have a dedicated separate loader.rc stashed in sys/boot/i386/loader/ Not sure of the cleanest way to do this for sparc64 (dup the loader.rc and make sparc64 drop it's own? or perhaps make sparc64 drop the i386 loader.rc?

[CFT] Kernel-Selection Enhancemnt to Boot Menu

No recompile needed, just drop the new forth files onto a HEAD or stable/9 box and reboot. -- Cheers, Devin _ The information contained in this message is proprietary and/or confidential.
