You have UUID labels in the LUKS header. In Debian at least, you have quite good support for LUKS. hal/hotplug recognizes that a LUKS partition was added to the system (it probes USB stuck for the LUKS header). In case this is found it adds it to the system. I'd say it wouldn't be hard to extend this with a map from UUID->label. Try to start with 60-persistant-storage.rules (at least it's named that in udev-114 on Gentoo). It calls "vol_id --export", which only finds the LUKS UUID when invoked with a LUKS dev. Try to replace vol_id by a script that maybe works like this. #!/bin/bash vol_id --export $1 > /tmp/somefile source /tmp/somefile ID_FS_LABEL=`grep $ID_FS_UUID /etc/uuidmap | cut -f2 -d:` cat /tmp/somefile | sed -e s/ID_FS_LABEL.*/ID_FS_LABEL=$ID_FS_LABEL/ # you might have to add ID_FS_LABEL_ENC/ID_FS_LABEL_SAFE. when putting stuff like youruuid: yourlabel into /etc/uuidmap you should than find LUKS disks under /dev/disk/by-label/yourlabel/ In case that actually works, please add that info to the wiki. http://www.saout.de/tikiwiki/tiki-index.php?page=LUKS (Christophe, we really gotta change the default layout!) -- Fruhwirth Clemens - http://clemens.endorphin.org --------------------------------------------------------------------- dm-crypt mailing list - http://www.saout.de/misc/dm-crypt/ To unsubscribe, e-mail: dm-crypt-unsubscribe@xxxxxxxx For additional commands, e-mail: dm-crypt-help@xxxxxxxx
