That's exactly what I would like to have! I have a working solution, but |
| 33 |
using UDEV would seem more adequate. |
| 34 |
|
| 35 |
But: I cannot find a serial number for my hard drives in the output. And |
| 36 |
shouldn't there be a file named 'serial' in /sys? I have some, but not |
| 37 |
for my block devices, only for USB and in /sys/{bus,pci}/drivers/. |
| 38 |
|
| 39 |
BTW, sys-fs/udev-187 does not have the 'udevinfo' command, it seems to be |
| 40 |
'udevadm info' now. |
