external USB encryption key (dm-crypt and luks) - help!

TornadoTDi · 2008-08-25 15:10:05

Hi, I've been following the 'System Encryption with LUKS for dm-crypt' wiki during my new laptop install - but am stuck on one bit.

On this line:

echo 'KERNEL=="sd*", ATTRS{serial}=="$SERIAL", SYMLINK+="$SYMLINK%n"' > /etc/udev/rules.d/8-usbstick.rules

What do I put in for the $SYMLINK%n ? is this a link to /dev/sd .. something? Or is it a name for the device?

Many thanks in advance for any help!

I may be wrong, but I don't think you need to put anything there, just leave that line the way it is

Thanks for your reply. The wiki page does say:

"Replace $SYMLINK and $SERIAL with their respective values. %n will expand to the partition (just like sda is subdivided into sda1, sda2, ...).".

Now, the $SERIAL part can be obtained, but it's not clear what form the $SYMLINK variable is in...
