I'm not familiar with strace (I'm just an imaging app programmer [on doze]).

The patch I'm referring to is on this page:

I believe that since RH now defaults to using I2O_block for raid controllers instead of dpt_i2o from adaptec, then their shipping version of grub would have this patch applied.

Perhaps the patch could be reviewed, fixed and applied to GRUB2 and Legacy by folks who know grub (not I).

On the two servers I've installed RHEL 4 on, I've had trouble with grub. It's the combination of grub and the new I2O_block driver. I suspect the grub patch to support I2O is lacking.

Are you referring to a particular patch?

I was wondering if Grub 0.95 or 2.0 has a facility to trace the changes being made when grub-install is being ran. After an install or an update I had to run grub-install to get it to boot again. In theory, this shouldn't be neccessary. Since it was, I thought it would be useful to be able to compare the areas of the disk written to during grub-install with what was written there before so that I could trace down the problem.

I don't see anything like that in GRUB2's grub-setup.c, but it is a good idea.

I also don't see anything like that in GRUB Legacy's "grub". You could always strace...
