Start container as user

[ptulpen]

Hello,
we would like to build up a jupyter system on mesos with this spawner.
What I am currently not sure about: we would like to create a work folder for each user on an NFS share.
Since we have a fixed user with ID 1000 I think this is quite difficult.

In other similar cases we start the container as the user so we can mount as the user.
Is this possible?
Maybe it is enough to create the folder by jupyterhub if it does not exist. (like a mkhomedir) and the user can stay the default user
Has anyone done this before or further ideas?
