> findmnt -P -o source,target,uuid | grep -Ee'REGEX4UUID'

Thanks. This combined with another test might also work.
# blkid -U 40d81969-8f9d-4964-b214-87bcf273192a
/dev/sdb3

Might be something more direct. Parallel to this.
if findmnt -rn -s UUID=40d81969-8f9d-4964-b214-87bcf273192a ; then

I don't want to test whether mounted. Test only existence.

Thanks,                       ... P.
