Bug#508567: grub2: Wrong automatic generation of grub.cfg makes only one partition bootable

[Alex Dănilă]

Package: grub2
Version: 1.96+20080724-12
Severity: important

*** Please type your report below this line ***
A typical Debian grub.cfg looks like this:
### BEGIN /etc/grub.d/10_linux ###
set root=(hd0,5)
search --fs-uuid --set fa23b4c4-ede2-4b69-8daa-4e405dc8ea36
menuentry "Debian GNU/Linux, linux 2.6.26-1-amd64" {
	linux	/boot/vmlinuz-2.6.26-1-amd64 
root=UUID=fa23b4c4-ede2-4b69-8daa-4e405dc8ea36 ro usbcore.autosuspend=1
	initrd	/boot/initrd.img-2.6.26-1-amd64
}
[...]
### END /etc/grub.d/10_linux ###
This is wrong because the set root command should stay inside the 
menuentry.
The effects are bad mostly through their didactic effects, trying to use 
these method to add another distribution will make only the last 
distribution in the list bootable (as can be seen in the grub.cfg that 
comes with the report.
Debian Unstable updated today.
