GuixSD: cryptsetup luksFormat hangs when udevd is running |
Date: |

Setting up luks encrypted partitions with cryptsetup doesn't work when udevd is
running.
cryptsetup luksFormat got stuck waiting on some semaphore to turn to zero
According to http://www.saout.de/pipermail/dm-crypt/2013-November/003619.html
this is a udev issue, so i killed udevd and after that it worked
I assume it's some configuration issue with udev, but I don't really know
enough about this stuff to pinpoint where exactly the problem lies
I'm using the GuixSD 0.8.2 image, if you need any more information about my
setup, feel free to ask

Indeed, we were missing the udev rules for device-mapper. Commit
e1ad6bf fixes that (tested in a VM as produced as by ‘guix system vm
gnu/system/install.scm’.)
If you have a working Guix installation, you can try rebuilding the
image by yourself from a checkout of Guix master, with something like:
guix system disk-image --image-size=850MiB gnu/system/install.scm
Alternately, as a workaround, you could to the installation in two
steps:
1. Install without encrypted devices.
2. Boot the installed system and run ‘cryptsetup luksFormat’.
3. Run ‘guix system reconfigure’ with the configuration that you want.
Thank you!
