[Christopher Larson]

From: Christopher Larson <chris_larson@mentor.com>

This is the final of three pull requests / patch series from Mentor's queue of
changes destined for oe-core master (not jethro). This series includes a small
number of improvements which may be more contentious or may require more
consideration and review.


The following changes since commit e44ed8c18e395b9c055aefee113b90708e8a8a2f:

  build-appliance-image: Update to jethro head revision (2015-11-03 14:02:57 +0000)

[PATCH 1/4] linux-dtb.inc: use absolute upd-alt paths

[Christopher Larson]

From: Christopher Larson <chris_larson@mentor.com>

This works around a limitation of the chkconfig update-alternatives, so it
works with all our update-alternatives providers.

I know this change is old and has been in for over a year...

But the side-effect of it is that it breaks NFS-boot due to absolute DTB 
symlinks. We had to implement a local workaround to switch them back to 
relative links.

Is there another way to fix the original issue w/o absolute links?

I expect so. I’d be fine with dropping this, it was a workaround more than
anything else anyway.

Ok, someone just changed it, works for me :)

[PATCH 2/4] opkg-utils: add update-alternatives PACKAGECONFIG

[Christopher Larson]

From: Christopher Larson <chris_larson@mentor.com>

This lets someone use a different update-alternatives-native provider. Without
this available, they'll step on one another in the sysroot unconditionally,
since we need to build opkg-utils-native for ipk based builds regardless.

Re: [PATCH 2/4] opkg-utils: add update-alternatives PACKAGECONFIG

[Robert Yang]

Hi Chris,

I've afraid this patch can't work well, when opkg-utils doesn't provide
virtual/update-alternatives, then chkconfig would be built and there would
be dependency loops for example,

PACKAGECONFIG = "python"
$ bitbake core-image-minimal

Afaict it should work for the native case, just not target, if you use the
chkconfig-alternatives-native recipe. In meta-mentor we have that recipe
for target as well, to cover both cases, I'll see about submitting that.
We've been using the chkconfig update-alternatives implementation for a few
releases now.

If I understand correctly, maybe we need make PACKAGECONFIG only
be available for opkg-utils-native ?

[PATCH 3/4] systemd: add myhostname to nsswitch.conf

[Christopher Larson]

From: Christopher Larson <chris_larson@mentor.com>

We don't need nss-myhostname on systemd systems, because systemd already
provides myhostname, but we weren't configuring nsswitch to use it. Being able
to resolve the hostname is useful for a number of different applications, so
enable it using the same postinst/prerm bits which are in nss-myhostname.

This seems to solve my xfce4-terminal delay - thanks. I have a
questions regarding this patch: As soon as basefiles are updated
resolving stops working - right? So why not handle at basefiles based
on systemd distro setting?

As far as I know, nsswitch.conf is flagged as a conffile (actually in
master everything in /etc/ will be), so once it's modified externally (in
this case, by the systemd recipe), the original package which installed the
file won't blindliy overwrite those changes.

I have this and a similar change for resolved in an append at work. Would
others be interested in that too?

I'm sure there are folks that would find that interesting. I'm sure not
everyone uses resolved, but I'm sure we want it to work well for folks taht
do want to use it.

Cool. I'll post my change. nss_resolve can be used unconditionally if it's
there. If resolved isn't running it falls back to nss_dns.

[PATCH 4/4] systemd: arrange for volatile /etc/resolv.conf

[Christopher Larson]

From: Christopher Larson <chris_larson@mentor.com>

On sysvinit systems, volatiles is configured to make /etc/resolv.conf symlink
to a file in a volatile path, which lets us write to /etc/resolv.conf for
read-only-rootfs. For systemd, this isn't set up unless we enable
systemd-resolved, which we don't by default. When it's not enabled, create the
/etc/resolv.conf symlink and ensure the volatile path is created on boot with
tmpfiles.d.
