[PATCH] experimental CALLOUT script for devfs ide node creation with cd, disc, part
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
