[lxc-users] lxc config device add

[Spike]

Hi,

I've just gone through this recently to expose a data/ partition and found
a bunch of docs with several different methodologies (and some scripted
utils):

- https://github.com/lxc/lxd/issues/2025 (explains the theory/problem)
- https://github.com/lxc/lxd/issues/2526
- https://gist.github.com/nottrobin/a66d3d5b9722149136d7fc6f93dae59f
 (Script)
- https://github.com/antitoine/lxd-functions
- https://gist.github.com/bloodearnest/ebf044476e70c4baee59c5000a10f4c8
(another
script)

for myself I arrived to the same conclusion as Sjoerd, the easiest thing
was to chown the dir on the host to match the uuid on the guest. If you
read the links above you'll understand the uuid mapping and by running ls
on the container's data you can double-check your root's uuid on the guest
(by default it should be 100000 on ubuntu). After a chown/chgrp root will
have access to it on the guest and will be able to further add dirs for
specific users. Do not that even root on the guest won't be able to chown
the folder itself so if you want the entire partition to be owned by mysql
you need to find mysql's uid and chown on the host to that.

hope that helps,

Spike
