[PATCH] ide-devfs.sh update
Attached is a patch for ide-devfs.sh, The script is merged with the one from Martin Schlemmer, and cleaned up by him, to create both types of symlinks with one single rule: CALLOUT, BUS="ide", PROGRAM="/etc/udev/ide-devfs.sh %k %b %n", ID="hd*", NAME="%1c", SYMLINK="%2c %3c" /udev/ |-- cdroms | `-- cdrom0 -> ../hdc |-- discs | |-- disc0 | | |-- disc -> ../../hda | | |-- part1 -> ../../hda1 | | |-- part2 -> ../../hda2 | | `-- part4 -> ../../hda4 | |-- disc1 | | |-- disc -> ../../hdb | | `-- part1 -> ../../hdb1 | `-- disc2 | |-- disc -> ../../hde | `-- part1 -> ../../hde1 |-- 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
