# no clustering needed for this demo
Would you like to use LXD clustering? (yes/no) [default=no]: 
# since this is a new install, there is no existing storage pool, which is where the filesystem gets stored
Do you want to configure a new storage pool? (yes/no) [default=yes]: 
# can be any name, which would probably help with connecting new instances to an existing pool, leaving default for now
Name of the new storage pool [default=default]: 
# btrfs gives you fancy things like snapshots and volume management, but "dir" just uses a local directory for simplicity
Name of the storage backend to use (lvm, btrfs, dir) [default=btrfs]: dir
# "which is "metal access assess server"?" dunno - he didn't use it
Would you like to connect to a MAAS server? (yes/no) [default=no]: 
# yes, create a bridge, which will allow the new envs to access the network
Would you like to create a new local network bridge? (yes/no) [default=yes]:
# Name it anything you like, I'm leaving it default
What should the new bridge be called? [default=lxdbr0]: 
# auto address ranges are fine
What IPv4 address should be used? (CIDR subnet notation, “auto” or “none”) [default=auto]: 
What IPv6 address should be used? (CIDR subnet notation, “auto” or “none”) [default=auto]: 
# It will be available on this machine, but should it be exposed to other machines?
Would you like the LXD server to be available over the network? (yes/no) [default=no]: 
# this will automagically update your image under your feet. choose wisely.
Would you like stale cached images to be updated automatically? (yes/no) [default=yes]: 
# spew this all back to me?
Would you like a YAML "lxd init" preseed to be printed? (yes/no) [default=no]:
