Bug#532653: grub2: debconf extracts only the first command argument to the linux kernel from /boot/grub/menu.lst

[Michael Stapelberg]

Package: grub2
Version: 1.96+20090317-1
Severity: normal

When installing grub2, one is first asked whether to chainload grub, afterwards which arguments should be configured
for the linux kernel. In the last question, the text field only shows the first argument, in my case
acpi_sleep=s3_bios, but the arguments afterwards (usbcore.autosuspend=1 rootfstype=ext4) are not shown.

Given that mostly experienced users will install grub2 i’m filing this bug as severity: normal, however for
example the rootfstype=ext4 option would prevent my system from booting if not specified.
