Description Alexei Volkov 2010-03-08 11:00:11 UTC
I wood like to to get bootable cd with auto selectable amd64/i386 boot kernel, but did not find any solution in current boot facilities.

For instance, if i have a bootable cd with two kernels located /boot/kernel.amd64
and /boot/kernel.i386 accordingly it looks pretty logical to have loader.conf  line like /kernel=kernel.${hw.machine} and it let boots up amd64 kernel if long mode supported.

Fix: I found that the boot facilities has everything to setup the hw.machine kernel environment variable, but does't do that.

Is it right to setup hw.machine kernel variable with a patch attached?

Patch attached with submission follows:
How-To-Repeat: append loader.conf with line 


andd see nothing will happend event you have kernels in a assumed path.
