Here is a experimental CALLOUT script for udev to create devfs nodes
for IDE-devices. Not that I need these, I just wanted to see if it works :)
The script is really stupid, no error handling, nothing more than
absolutely needed. The rule uses the 'k' format char of the previous
patch. The %D is not used, so the user can have disc or disk :)
this single line:
CALLOUT, BUS="ide", PROGRAM="/etc/udev/ide-devfs.sh %k %b %n", ID="hd*", NAME="%1c", SYMLINK="%2c"
creates the following on my machine with two hard disks, one DVD and a PCMCIA-compact-flash inserted:
/udev
|-- hda
|-- hda1
|-- hda2
|-- hda4
|-- hdb
|-- hdb1
|-- hdc
|-- hde
|-- hde1
`-- ide
|-- host0
| |-- bus0
| | |-- target0
| | | `-- lun0
| | | |-- disc -> ../../../../../hda
| | | |-- part1 -> ../../../../../hda1
| | | |-- part2 -> ../../../../../hda2
| | | `-- part4 -> ../../../../../hda4
| | `-- target1
| | `-- lun0
| | |-- disc -> ../../../../../hdb
| | `-- part1 -> ../../../../../hdb1
| `-- bus1
| `-- target0
| `-- lun0
| `-- cd -> ../../../../../hdc
`-- host2
`-- bus0
`-- target0
`-- lun0
|-- disc -> ../../../../../hde
`-- part1 -> ../../../../../hde1
