Comment 2 for bug 16737

Well, i feel that the full canonical path (@f2000000 and co) is not (at all or
easily) available from the devfs representation of the devices. I don't know how
you handle that with non-devfs hoary and later installer, but it should be
possible to get the full canonical path from /sys or something such.

$ for i in `find /sys -name devspec`; do more $i; done

Gives the canonical device name of all pci devices :

/pci@C0000000/display@8,1
/pci@C0000000/display@8
/pci@C0000000/host@0
/pci@80000000/ethernet@D
/pci@80000000/pci1106,3068@C,6
/pci@80000000/sound@C,5
/pci@80000000/other@C,4
/pci@80000000/usb@C,3
/pci@80000000/usb@C,2
/pci@80000000/ide@C,1
/pci@80000000/isa@C
/pci@80000000/usb@6,2
/pci@80000000/usb@6,1
/pci@80000000/usb@6
/pci@80000000/scsi@5
/pci@80000000/firewire@1
/pci@80000000/host@0

But we need then to match those with the ones where our d-i path is on.

I believe that is you go into /sys/block/<device>/device, and do a :

/sys/block/hda/device$ more ../../devspec
/pci@80000000/ide@C,1

you find the full canonical path.

Naturally, we couldn't do this in debian, since debian was still supporting 2.4
kernels, but this should be no major problem in ubuntu.
