[lxc-users] Manually building an image

[Robert Johnson]

I have a particular distribution based on CentOS 7 that I would like to 
turn into a LXD container. The post from Stephane Graber here below has 
a section titled Manually building an image, but it gives some pretty 
generic steps that I'm not entirely familiar with. I'm hoping someone 
could point me in the right direction.

1. Generate a container filesystem. This entirely depends on the 
distribution you’re using. For Ubuntu and Debian, it would be by using 
debootstrap.

If anyone has an documentation on "Generating a container filesystem", 
I'm all ears. Specifically pertaining to CentOS 7 would be great.

Could I just create a tarball of / ?

2. Configure anything that’s needed for the distribution to work 
properly in a container (if anything is needed).

How would I know if a distribution needs any special attention?

 From there on, the process seems pretty straight forward.
