Public bug reported:
When setting resize_rootfs to 'noblock', cloud-init should fork a new
process and continue with it's own initialization process. However, it
seems that this is currently broken, as you see from these logs that it
still blocks on it:
Jul 7 12:34:20 localhost [CLOUDINIT] cc_resizefs.py[DEBUG]: Resizing (via
forking) root filesystem (type=ext4, val=noblock)
Jul 7 12:34:20 localhost [CLOUDINIT] util.py[WARNING]: Failed forking and
calling callback NoneType

Also, when looking at timings, you can see that it was blocked on it for
the whole time
