solved]Howto mount a luks partition if devicename is unknown

[pactoo]

Hello,

I have an external, luks encrypted harddrive, which I would like to mount upon calling a script, that asks for the password and does all the luksopen stuff.

Now the problem is, as this drive is usually plugged into a running system, so the device name is unknown to the script. Sometimes it will be /deb/sdb, other time /dev/sde a.s.o.
Currently I look up the new device manually and pass it as an argument to the script. Really Bothersome. Especially as I intend to automount those partitions sooner or later using a keyfile on a smartcard.
The harddrive has three different partitions, each to be mounted in its own, predefined mountpoint.

Now with cryptsetup luksUUID /dev/sdx1 I can identify the partition, with smartctl -i /dev/sdx I can even read the serialnumer of the drive and identify it this way. But both need the devicename, which I do not have.

With normal partitions this is no problem, as I can mount using the filesystem UUID or LABEL. With usb drives it is usually no problem, too, as I can assign a unique device name, based on the serial numer of that usb device, which is recognised by udev.

As udev is however unable to read the serialnumber of a (s)ata drive, I cannot go this way. So I wonder wether there is a possibility, that hal does some of this stuff. Wether it would be possible to have hal call a script which it passes the device name to.

Other alternatives would be welcome, too. Like, is there a way to make this happen in kde, that upon insertion of an luks drive a dialog opens, that simply asks for a password and mounts the partition in correct mount point.

There is a possibility to name a harddrive according to its serial:
