Hi Adrian,
The following information is from a PPC G5, 2.2 GHz, 2 processors.
Disk /dev/sda: 931.53 GiB - internal SATA disk
Disk /dev/sdb: 465.78 GiB - internal SATA disk
Disk /dev/sdc: 298.9 GiB - firewire disk (front built-in firewire)
Disk /dev/sdd: 698.65 GiB - USB disk (back built-in USB)
Disk /dev/sde: 16.98 GiB - SCSI disk (ATTO UL3D PCI-X)
The ofpathname results in Debian SID and Debian 7.8 were slightly
different. I don't have ofpath in Debian SID, only Debian 7.8.
