- Update to version 2018.4:
+ A quick turnaround after 2018.3 to include one main PR:
gh#ostreedev/ostree#1508.
+ "switchroot: Ensure /run/ostree-booted is created even without
initramfs".
+ This fixes ostree when booting without an initramfs. Thanks to
@akiernan for the bug report and helping review the fix! I'm
working on enhancing the test suite, which will help in adding
some coverage here.
- Changes from version 2018.3:
+ Keeping up with our ~monthly cadence. A variety of contributors
here again, it's great to see! There's two notable features,
and a variety of non-critical bugfixes.
+ On the features side we have:
- sysroot: Add concept of deployment "pinning".
- ostree: introduce PAYLOAD_LINK object type.
- lib/fetcher: Allow clients to append to User-Agent.
+ By default libostree prunes older deployments; the pinning
feature allows you to explicitly retain them until unpinned.
This is useful for major version updates.
+ The PAYLOAD_LINK functionality allows libostree to do
content-based deduplication. Previously, if e.g. a file changes
in metadata (mode, owner, xattrs such as SELinux labels), we
can't make a plain Unix hardlink, and hence by default end up
with a new copy on disk. However, the Linux kernel has
standardized "reflinks" and some filesystems support them,
including modern versions of XFS. When reflinks are available,
this functionality causes libostree to compute a content-only
payload, and when importing an object, if it matches in content
with an existing object, to use reflinks to deduplicate, while
using different inodes.
+ Finally, the HTTP User-Agent API is intended for higher level
tools linking to libostree where one wants to expose the app
version as well.
+ Beyond that, as mentioned above we have a variety of
non-critical fixes such as memory leaks, test suite
improvements, correctly printing the "would be pruned" size
when using prune --no-prune, etc.
- Changes from version 2018.2:
+ We're keeping up with the approximately-monthly release cycle.
There's mostly a collection of smaller fixes here, with some
enhancements. I'm biased but my personal favorite is
gh#ostreedev/ostree#1438 since it makes the output of findmnt
rather significantly nicer on this workstation where I have
container tooling creating sub-mounts in /var that are no
longer replicated in /sysroot.
+ For the embedded space, gh#ostreedev/ostree#1411 for devicetree
support is likely interesting, and is related to a discussion
on the mailing list:
https://mail.gnome.org/archives/ostree-list/2018-February/msg00001.html
+ Jonathan's PR gh#ostreedev/ostree#1441 to add callback
filtering to checkout was necessary for us to re-implement some
hairy logic from librpm around "file coloring"; see
projectatomic/rpm-ostree#1227 We're getting quite far along now
in having rpm-ostree be a truly hybrid system, supporting the
existing RPM ecosystem.
+ Marcus definitely wins the "lines changed" count this cycle by
adding SPDX-License-Identifier to all of the C source files
(gh#ostreedev/ostree#1439). This happened because we relicensed
the documentation to dual CC BY-SA and GFDL in
gh#ostreedev/ostree#1432 to enable a Wikipedia page which I
just noticed exists now! (forwarded request 602906 from iznogood)
