Hi folks! Time for a first F24 Alpha blocker bug status mail.

tl;dr work summary
------------------

QA folks:
* help figure out what's going on in #1315541
* ensure all Alpha validation tests are covered with recent composes

anaconda devs:
* review/merge https://github.com/rhinstaller/anaconda/pull/542 for
#1315434
* figure out what's going on in #1315541
* be part of the committee or whatever that decides what to do about
#1313085 (bcl)

systemd and NetworkManager devs:
* be part of the committee or whatever that decides what to do about
#1313085 (bcl)

detailed per-bug info
---------------------

1. https://bugzilla.redhat.com/show_bug.cgi?id=1315434 - anaconda/pungi - POST
   Fedora 24 x86_64 network installs get i686 kernel and fail to boot

I've posted a patch for this from the anaconda end that needs review
and merge: https://github.com/rhinstaller/anaconda/pull/542
I think I also saw some discussion of what the issue is in Pungi, so it
looks like we should be able to fix this from both ends.

2. https://bugzilla.redhat.com/show_bug.cgi?id=1313085 - systemd - NEW
   Name resolution fails (resolv.conf is a broken systemd symlink) on livemedia-creator live image

This is the latest incarnation of an ongoing issue which involves
something of a difference of opinion between systemd devs on the one
hand and NetworkManager and anaconda folks on the other. Briefly put,
if there is no /etc/resolv.conf when systemd-tmpfiles runs, it creates
it as a symlink pointing to ../run/systemd/resolv/resolv.conf , which
is the location where systemd-resolved would put a resolv.conf if it
was in use. But we don't use systemd-resolved, we use NetworkManager.

When NetworkManager starts up, if /etc/resolv.conf does not exist or
exists as a regular file, it will replace it with a symlink to its own
location (/var/run/NetworkManager/resolv.conf). But if /etc/resolv.conf
exists as a symlink pointing anywhere else, NM will leave it alone.
This is by design, and extensively commented in the code - https://cgit
.freedesktop.org/NetworkManager/NetworkManager/tree/src/dns-manager/nm-
dns-manager.c#n604 .

The reason this changed now is the switchover from livecd-creator to
livemedia-creator. livecd-creator creates an empty /etc/resolv.conf in
the live images when producing them, which meant systemd-tmpfiles
wouldn't touch the file and NetworkManager would replace it with a
symlink to its resolv.conf and networking worked. livemedia-creator
does not do this; a livemedia-creator-produced live image contains no
/etc/resolv.conf at all.

So when the live image is booted, systemd-tmpfiles creates
/etc/resolv.conf as a symlink, systemd-resolved isn't used,
NetworkManager refuses to replace the symlink, and the consequence is
that /etc/resolv.conf is a dangling symlink pointing to a location
managed by a daemon that isn't being used, and there's no name
resolution.

We've hit this issue in various circumstances and always had an
acrimonious dispute about who's wrong about what and who ought to "fix
it". I guess we get to do that again. I don't care who wins, but
someone needs to change something.

3. https://bugzilla.redhat.com/show_bug.cgi?id=1315541 - anaconda - NEW (proposed)
   pyanaconda.packaging.PayloadInstallError: Failed to mount the install tree

This is only a proposed blocker, but it looks pretty likely to be
accepted. Recent KDE live images boot fine and can start anaconda, but
crash when they reach the hub screen. This does not affect Workstation
lives, it seems. We need to figure out what's going on here.
