Hi,
stat --format='%D' /
will give you the major & minor device of the root file system, if that
is what you need.

I am working on a small project and I have the need to identify the root volume

I can quickly and easily do a 'blkid' and get a list of block devices attached and I can
identify the actual drives (major number 8) and I can do the usual check for
"/", etc. but I keep feeling that I'm missing some not so fringe cases where
the boot/root volume may not be screamingly obvious.
I am wondering if there's some "proper" tool/utility that I can ask directly
and have the system return the authoritative answer. Of course, finding it in /proc is
reasonable since it's much more likely to be an authoritative answer.
Anyone have any advice or thoughts?
Thanks in advance for any help offered.
Could you iterate through the available block devices, mounting each and
checking for the directories that LSB requires? Minimally, I think this
would be /usr, /bin, /etc, and /lib. /etc and /usr should be enough to
differentiate it from other filesystems that also contain bin and lib
directories.
