Post drive migration: boot device: <unknown>

[Bradley Pearce <bottleworksnet%gmail.com@localhost>]

Hi.
I just moved a standalone scsi boot drive to a raid system (sd0 to
ld0).  Long story short, it takes quite a custom kernel to do this.
/etc/fstab was updated to ld0.

/dev/MAKEDEV all  was run.

installboot -v /dev/rld0c /usr/mdec/bootxx /ofwboot
File system:         /dev/rld0c
File system type:    ffs (blocksize 16384, needswap 0)
Primary bootstrap:   /usr/mdec/bootxx
Secondary bootstrap: /ofwboot
Bootstrap start sector: 4
Bootstrap byte count:   1824
Bootstrap block table:  118 entries of 16384 bytes available, 4 used:
616032 616064 616096 616128
Writing bootstrap

It boots, but during boot, it doesn't know the boot device, root
device, file system type, and init path.  I can enter ld0 for root
device, ffs for file system, and init path.

How do I reconfigure the system to remember this?
Right now, I have to enter it at each boot.

[     4.740066] boot device: <unknown>
[     4.740066] root device: ld0
[     4.740066] dump device (default ld0b):
[     4.740066] file system (default generic): ffs
[     4.740066] root on ld0a dumps on ld0b
[     5.670102] kern.module.path=/stand/macppc/9.3/modules
[     5.810110] init path (default /sbin/init):
[     5.810110] init: trying /sbin/init

Thanks,
