Lab 16.1: Misleading info in step using fdisk
Step 1 of this lab says "Create two 250 MB partitions of type logical volume (8e)". I believe 8e corresponds to "Linux LVM". Calling this a "logical volume" is probably misleading and a bit confusing, as the further steps describe creating logical volumes. The wording makes it sounds like you're creating logical volumes in step 1, when you're only creating a partition of a particular type that can be used by Linux LVM.
