Hi Sebas! Let me start off by thanking you guys for putting together this
detailed feedback for everyone. Comments inline:

Adam Israel (aisrael) and Abel Deuring (adeuring) have been working on the
Vagrant workflow bits, I'll let them comment here. It might be a good idea
for you to just sync with Adam directly over a call or hangout and let him
know specifically which areas you'd like to see fixed

(I'll combiine this with the cloning) - our overall speed story is
something that we've been looking at for this cycle from the top of the
stack down, hopefully someone can fill in the details on some of the other
work we've been doing here while I point out the ones I've been using

1.21 alpha has:

    enable-os-upgrade: false
    enable-os-refresh-update: false

This will let you skip a bunch of disk grinding when launching new
development instances. image-stream:daily might also help you out, see:
https://launchpad.net/juju-core/+milestone/1.21-alpha1 for more info.

I have also found that having /var/lib/lxc on a btrfs disk has helped with
speed tremendously with the lxc cloning, however we still have the issue of
hot/cold cache depending on what the charm does. Obviously "reinstall your
laptop" might not be ideal, but if you have a spare disk it might be worth
investigating. LXC containers on btrfs and an SSD is sooooo nice though.

We've utterly failed you by not fixing this bug, I'll mention it at our
weekly meeting today and we'll sort out something as soon as we can.

Someone just mentioned DHX, I think you guys will dig it:

This should help remove some friction right off the bat. Keep the feedback
coming!
