Some puttering around notes on Pulsar Linux.

Two things:

• the active development branch for Pulsar Linux is pulsar-x
• current development emphasizes the container-related images (cube-dom0, cube-essential, etc), not so much standard images like core-image-minimal

First, to support my standard GitHub workflow, I like to clone GitHub projects with the remote name github as I like to reserve the remote name origin for my fork of the project, to which I will push subsequent commits:

$ git clone \
    -b pulsar-x \
    -o github \
    --recurse-submodules \
