Permissions of docker user's home directory

[flylan]

Guest system version: Windows 10 professional
Virtualbox version: 6.1.6 r137129
Vagrant version: 2.2.7
Boot2docker.iso version: v19.03.5

I use boot2docker as the virtual system of vagrant. I need to set config.ssh.insert_key = true to use Rsync's shared folder mode.
However, due to the directory permission problem of /home/docker, the docker user cannot create authorized_keys in this folder, so I hope you can help to set the user of /home/docker as docker user

chown -R docker:docker /home/docker

Looks like we missed a few while updating /home/docker's contents -- try this patch:

I don't want to rebuild boot2docker.iso, because it needs energy to maintain. I hope the future version can fix this problem.I have noticed that boot2docker.iso has not released a new version for a long time. And tinycore Linux has released version 11. Will the next version fix this problem and apply tinycore 11?

Instead of rebuilding boot2docker.iso, I choose to generate the bootlocal.sh file at initialization time.My current solution is to create a bootlocal.sh file under /var/lib/boot2docker like:
#!/bin/sh
chown -R docker:docker /home/docker

So after I built boot2docker.box, other users can use Rsync to share folders through vagrant
