Subject: grub2-common: grub.cfg gains wrong root settings for multi-OS system

Package: grub2-common
Version: 2.02~beta2-22+deb8u1
Severity: normal

Dear Maintainer,

I have set the system up as follows
/dev/sda1 is a grub partition
/dev/sdb1 is Devuan 1.0 RC, NETINST install
/dev/sdc1 is Devuan 1.0 RC, DVD install
/dev/sdd1 is Devuan 1.0 RC, CD install

For all installs, I made it mount /dev/sda1 at /boot but only the
first install formatted it.

update-grub does collate all the OSs, but the final configuration has
the same 'root=...' arguments for all boot options, instead of the
different root options. And therefore that same OS will be booted
regardless of which one I choose.

Ralph.
