Year begins with a new release of PostX Gnu/Linux.
The 0.4 release notes still mostly apply. So, if in any doubt go here.
January 3rd 2017 edit: I had written echi=off to the 0.4 original release notes, which is wrong. It should be edd=off. Edd stands for Enhanced disk drive. Apologies for the mistake. Use edd=off in the case that the boot to live-environment hangs and does not continue. Now, the entry should also be correct within the original release notes.
