Weekly status for the week of the 2nd to the 8th of July.
Introduction
This week we added some more options to the “proxy” device in LXD, implemented container delete protection and fixes a variety of LXD issues. We also have a pull request now up for the new lxc-to-lxd which needs some help to go through testing before getting included.
On the LXC side, we fixed a number of logging issues, CGroup configuration and did a bunch of code refactoring to reduce duplication between commands/library.
We’re also still actively working on getting Centos moved over to distrobuilder, hopefully shortly followed by the ArchLinux images.
