--- Comment #2 from Ralph_Ulrich <eulenreich at gmx.de> ---
This was a longterm problem for me until I found googling:
#!/bin/bash
R=$(stat -c '%04D' / )
for f in $(find /dev -type b 2>/dev/null) ; do
    C=$(stat -c '%02t%02T' $f )
    [ "$C" = "$R" ] && ROOTDEVICE="$f" && break
done
echo $ROOTDEVICE
#---
But watching your nluug/2014-11-20 about capabilities that script I use to find
root would not work in a container which has no capability to see /dev/RAW
devices?
