Weekly status #110

Weekly status for the weeks of the 05th August to the 11th of August.


The primary focus for the last week was getting the LXD 3.16 release ready.

This includes the rework of Infiniband device support to our new devices framework. This is part of the ongoing process to migrate all of our device handling code into a common framework so that the different device type implementations are isolated from each other to make the code cleaner and less bug prone. It will also make it easier to add other types of devices in the future.

We have also added support for using shiftfs with custom storage volumes, meaning you can now run multiple containers in isolated UID/GID mode and still share a common host directory with them because LXD will shift the different container’s UID/GIDs back to the host’s equivalent.

Other LXD improvements this week include updating bash completion so that it works with more options, and standardising the tabular output format of the lxc CLI.

On the distrobuilder side, as well as several bug fixes, there was a performance improvement added to group consecutive package installs together with a single command call rather than install each package individually. However it still honours package install order.

Initial support for cloud variants of the various images we publish has also landed, those images will start showing up over the next few days and all feature cloud-init support.

Over time more images will become available with cloud-init built-in and we may eventually transition our default images to those cloud-init enabled ones (added size is the main downside).
