OSTree v2015.7 (critical update from v2015.4 on)

A new release of OSTree is now available via this GPG signed tag:


This is a critical update if you are using v2015.4, as a bug was introduced in that release
that caused unpredictable ordering of generated syslinux/uboot/grub2 bootloader entries.
If you are using a bootloader like gummiboot that directly reads the BLS, you should
be unaffected.

More details on this are available in:
If you want to backport the fix, it is:

If you have an affected system, likely the easiest course of action is to
edit the generated syslinux/grub2 bootloader configuration.  Scripts have
been developed to verify them:
and we will investigate enhancing them to actively fix the configuration.

If your operating system has an application mechanism (Docker, xdg-app, etc.), then
it should be possible to design a privileged application to address this.

Other changes in this release:
 - Performance enhancement for deployments; we now rely on syncfs() rather
   than individual fsync() calls.  In some storage scenarios the performance improvement
   can be dramatic.
- GPG: Always retrieve detached metadata, so we'll find newly added signatures
- GPG: Support for keys specific to remotes, rather than relying on the global /usr/share/ostree/trusted.gpg.d
- A new locking API (used for the commandline) so that concurrent invocations of e.g.
  `ostree admin upgrade` are safe.
- Other enhancements targeted for the Cockpit program and rpm-ostree
- The summary file can now be GPG signed as well, although this should be taken
  as a preview.  We have not yet decided how this interacts with the `gpgverify` boolean,
  and whether we should introduce a `gpgverify_summary`.
- Other changes to static deltas, which continue to evolve.  We aim to have GPG signed
  summary files in the next release, which will make static deltas more secure.
