v2018.5: Release 2018.5
@jlebon jlebon tagged this 15 May 14:42 
This release introduces a new automatic update policy: "ex-stage". As
hinted by the "ex" prefix, this is still an experimental option. This
builds upon a new "staging" feature in libostree which allows a pending
deployment to only be completed at reboot time. The major advantage of
this approach is that it finally addresses the long-standing `/etc`
merge issue (#40), where changes to `/etc` *after* a pending deployment
is created are not actually carried over at reboot.  We expect this
behaviour to become the default in the future. For now, one can either
use the "ex-stage" policy, or put this in their `rpm-ostreed.conf`:

    ```
    [Experimental]
    StageDeployments=yes
    ```

See the [ostree upstream release](https://mail.gnome.org/archives/ostree-list/2018-May/msg00003.html)
for more details around deployment staging.
PR: #1321

The way pending updates are displayed in the `status` output has been
reworked to be more intuitive. The pending diff and any addressed
advisories are now printed as part of the pending deployment itself
rather than a separate "Available update" section.
PR: #1350

Two changes for overrides:

 - core: Finish implementing `override replace ./kernel*.x86_64.rpm (#1346)
 - core: Don't rm-rf directories when doing overrides (#1341)

We fixed using `override replace systemd*.rpm`.  And the kernel
overrides in particular closes a longstanding gap - using ostree with
local or testing kernel builds is an obvious thing to support.

The `status` command now supports a new `-a`/`--advisories` to only
print details about outstanding advisories fixed in an available update.
PR: #1350

As usual, there were also a string of minor paper cut fixes and
enhancements.  For example, resetting an inactive override is now
possible. There were also multiple tweaks to the auto-updates mechanism
to make it more lightweight.
