------------------ Additional Follow-up Comments ----------------------------
The device of the mounted filesystem could be possibly obtained by stat(1) or 
stat(2). The C function interface is probably more portable as it should return 
predictable results  but the command is not even present on many systems.
At least comparing the results for / and /boot should work fine. Decoding the 
actual device node and physical disk partition may be harder.

Summary:  install-grub does not find the root device

Original Submission:  It is possible to specify the root device to the linux 
kernel as a number (and for some reason lilo does this). When it is specified 
this way (and possibly under other circumstances) the kernel would report that 
rootfs is mounted on / and install-grub script is not able to get the real 
device mounted on / just by scanning the output of df.

afaict the detection of root device by using df is still present in the cvs 
version of the script.
