I am using cryptsetup LUKS for storing encrypted office data on my USB memory stick (just in case I lose it). I recently installed Ubuntu 7.04 on one of my machines and wanted to open the encrypted partition using cryptsetup luksOpen, which failed with a rather strange
Unable to make device node for ‘temporary-cryptsetup-32733’
While searching around the net I found a lot of people asking the same question but hardly any answer, until I finally read this article
on the Ubuntu forum.
The solution to the whole problem is rather simple:
sudo mkdir /dev/.static/dev/mapper
With a little bit more verbose error message of cryptsetup I might have figured this out myself…
