Bug#535239: grub-pc: Multiple kernel root= paramaters

Package: grub-pc
Version: 1.97~beta3-1
Severity: normal
Hi
Time for another variation on this bug.
I was asked the debconf dialog about kopt, however the extracted value was empty.
I copied and pasted "root=/dev/hda5 ro" into the dialog. Next came the defoptions question.
Old value was
# defoptions=
The debconf dialog supplied (defaulted to ?) "quiet" which I accepted.
During reboot I checked the commandline and noticed
linux /boot/vmlinuz-2.6.30-1-686 root=UUID=24ed1821-c6b9-433b-9e03-b794a442e389 ro root=/dev/hda5 ro quiet
Given that grub-pc generated the root=UUID=24e... param perhaps it did extract the kopt
root=/dev/hda5 param successfully, but discarded it knowing it was going to add a root=
param anyway.
The kernel booted ok, so duplicate root params aren't necessarily a problem.

## default kernel options
## default kernel options for automagic boot options
## If you want special options for specific kernels use kopt_x_y_z
## where x.y.z is kernel version. Minor versions can be omitted.
## e.g. kopt=root=/dev/hda1 ro
## kopt_2_6_8=root=/dev/hdc1 ro
## kopt_2_6_8_2_686=root=/dev/hdc2 ro
# kopt=root=/dev/hda5 ro

## should update-grub create alternative automagic boot options

## should update-grub lock alternative automagic boot options
## e.g. lockalternative=true
## lockalternative=false

## Xen Linux kernel options to use with the default Xen boot option

## altoption boot targets option
## multiple altoptions lines are allowed
## e.g. altoptions=(extra menu suffix) extra boot options
## altoptions=(single-user) single
# altoptions=(recovery mode) single
## controls how many kernels should be put into the menu.lst
## only counts the first occurence of a kernel, not the
## alternative kernel options
## e.g. howmany=all
## howmany=7
# howmany=all
## should update-grub create memtest86 boot option
## e.g. memtest86=true
## memtest86=false
# memtest86=true
## should update-grub adjust the value of the default booted system
## can be true or false
# updatedefaultentry=false
## should update-grub add savedefault to the default options
## can be true or false
# savedefault=false
## ## End Default Options ##
