Identifying device by id would be useful, but I don't like those are exposed
as path, like /devices/iommu@f,e0000000/sbus@f,e0001000/..., which is too
complicated IMO.

What I'm thinking of is to have a file showing device class specific
information, like disk0.info, which would work like procfs.

        find /dev/mainbus0 -name 'disk*.info' -print | \
        while read f; do
                grep -q 'the-guid-i-am-looking-for' $f && echo found: $f
        done
