Bug#614002: grub-common: [kfreebsd] need a mechanism to pass sysctl parameters to kernel at boot time

[Marc Fournier]

Package: grub-common
Version: 1.98+20100804-14
Severity: wishlist


Some sysctl parameters of FreeBSD kernels can only be set at boot time.

With the traditional FreeBSD bootloader, you would define them in
/boot/loader.conf. With grub, this is done by adding a line such as this one
in /boot/grub/grub.cfg:

  set kFreeBSD.kern.maxswzone=67108864

The problem is obviously that /boot/grub/grub.cfg gets overwritten each time
update-grub2 is run.

The Linux variant of the package has this $GRUB_CMDLINE_LINUX option in
/etc/default/grub which gets included in the right places in
/boot/grub/grub.cfg.
We need the same sort of thing for kFreeBSD.

If it's just a matter of patching /etc/grub.d/10_kfreebsd to handle a
$GRUB_CMDLINE_KFREEBSD option in /etc/default/grub, I would be glad to submit
a patch. But maybe this should be discussed first, or coordinated with upstream
or whatever. Just let me know...

Cheers,
Marc
