Ola, change 'powerfull' to 'powerful' change 'tar xvjf ...' to 'tar -xvjf ...' (the manual says so) Reproducible: Always Steps to Reproduce: 1. 2. 3.
Portage Snapshot(s) on LiveCD: "Now extract the snapshot of your choice using the following construct." Is there really more than one? (What is the advantage?)
There currently is no LiveCD with multiple snapshots. I'll update the handbook to reflect this further (in the beginning we already mentioned that there was only one snapshot). The typo's have been corrected. The "xvjpf"/"-xvjpf" is no error (both will give the same result) but it is better to use a consistent option-handling, i.e. with dashes. Thanks for the feedback!
