Bug#858943: unblock: systemd/232-22

Package: release.debian.org
Severity: normal
User: release.debian.org@packages.debian.org
Usertags: unblock

Hello release team,

since 232-19, a couple of fixes accumulated which we'd like to see enter

As this potentially affects the installer, I've CC debian-boot aka KiBi.

A complete debdiff is attached.

The changelog + annotations follows. Sorry if it's a bit verbose.

> systemd (232-22) unstable; urgency=medium
>   [ Martin Pitt ]
>   * resolved: Disable DNSSEC by default on stretch and zesty.
>     Both Debian stretch and Ubuntu zesty are close to releasing, switch to
>     DNSSEC=off by default for those. Users can still turn it back on with
>     DNSSEC=allow-downgrade (or even "yes").


(not relevant for the installer)

According to Martin, the DNSSEC in resolved still triggers too many
issues so it's not safe to enable by default.
Do note, that resolved in Debian is not enabled by default though. So
it's a low risk change which errs on the side of being conservative.

>   [ Michael Biebl ]
>   * Add Conflicts against hal.
>     Since v183, udev no longer supports RUN+="socket:". This feature is
>     still used by hal, but now generates vast amounts of errors in the
>     journal. Thus force the removal of hal by adding a Conflicts to the udev
>     package. This is safe, as hal is long dead and no package depends on it
>     anymore.


(not relevant for the installer)

This is a potentially odd one. hal has been removed in jessie, but
apparently some users still have it installed after upgrading from
previous releases. This now leads to massive amounts of error messages
in the journal (basically on every uevent). So forcing the removal of
hal seems justified.
There is a slight catch: the Conflicts could potentially lead to udev
not being upgraded or udev removed in favour of keeping hal.
But: since no other package depends on hal anymore and lots of packages
depend on udev this scenario is rather unlikely. I did several upgrade
tests and was not able to trigger such a condition. In all cases, hal
was removed as intended.

(not relevant for the installer)

A rather obvious 3 line fix

>     It doesn't really add much value in normal operation and just spams the
>     log. (Closes: #858197)


(not relevant for the installer)

While resolved is not enabled by default in Debian, if you do it
manually, it was spamming the journal. It's a low risk one-line change.

(not relevant for the installer)

Lot's of users where confused by error messages in the journal, if
plymouth is not installed (which is the default in Debian).
While the error message is harmless, it's better to simply avoid it

>   * rules: Allow SPARC vdisk devices when identifying CD drives
>     (Closes: #858014)


(might be relevant for the installer)

Requested by a porter, didn't see a good reason not to include it.
Low-risk change.

> systemd (232-20) unstable; urgency=medium
>   [ Martin Pitt ]
>   * debian/gbp.conf: Switch to "stretch" branch

ignore, not relevant

>   * udev: Fix /dev/disk/by-path aliases for virtio disks. (Closes: #856558)


(might be relevant for the installer)

Quoting Martin: "this is reasonably straightforward and also important to
get fixed in Stretch"

>   * udev: Create persistent net names for virtio CCW devices.
>     This only affects s390x as only this has CCW devices. This provides
>     stable network interface names for those and avoids changing the names
>     on updating Stretch to Buster. (Closes: #856559)


(might be relevant for the installer)

This only affects s390x, so regression potential is low and it's
important to get into stretch, otherwise we'd have migration issues in
buster (as names would change, which would be ugly)

>   * Move systemd.link(5) to udev package.
>     .link files are being handled by udev, so it should ship the
>     corresponding manpage. Bump Breaks/Replaces accordingly. (Closes: #857270)


(not relevant for the installer)

Low risk change.

>   [ Michael Biebl ]
>   * Avoid strict DM API versioning.
>     Compiling against the dm-ioctl.h header as provided by the Linux kernel
>     will embed the DM interface version number. Running an older kernel can
>     lead to errors on shutdown when trying to detach DM devices.
>     As a workaround, build against a local copy of dm-ioctl.h based on 3.13,
>     which is the minimum required version to support DM_DEFERRED_REMOVE.
>     (Closes: #856337)


(not relevant for the installer)

This affects mostly users running a custom or older kernels.
The changelog should be self-explanatory. The last bump of the DM
interface version was in 4.8 and we don't want to to enforce that
as minimal kernel version.

packaging issue, not really relevant

straightforward fix which was requested by a user. Didn't see a good
reason not to cherry-pick this patch.

packaging issue, git-cherry-pick is used internally.

Thanks for reading/listening. Keep up the stellar work.
