What is 'vol_id' ?
That is the old way. It was superseded by 'blkid'. That comment must
have been left behind and not updated. Instead of running vol_id
--uuid try running blkid.
man blkid
If that comment is still occurring on a fresh installation then it
warrants a bug report to get it updated.
The context suggests that it is an executable program that is run
from the command line, but there is no such object in the search
PATH.
IIRC that came through the Ubuntu path and would have existed there in
/lib/udev/vol_id but now for all uses you want to map that to blkid.
