Building Rawhide(f18) for PPC

I have run into the following issues:

(informational) you need to be running Fedora 17 to run a rawhide mock shell

Your host OS needs to have an rpm version that supports usermove. Also, your host OS is used when files are mounted.

[dwa] Fetch the version of rpm from the builder repos, or update to RHEL 6.3, rpm 4.8.0-27.el6 supports usrmove.

no source repo for rawhide

This is used when downloading source rpms to rebuild when fixing problems. A defect will be written.

cat << __EOF__ >> /etc/yum.conf

[fedora-source]
name=fedora-source
mirrorlist=http://mirrors.fedoraproject.org/mirrorlist?repo=rawhide-source&arch=ppc64
failovermethod=priority
__EOF__

(informational) yum not installed during mock --init

[dwa] Edit your mock config files, look at the config_opts['chroot_setup_cmd'] line. or use 'mock -r foo --install <package name>' instead of yum within the chroot.

loop devices not created during mock --init

You have to run the following inside the shell:

MAKEDEV loop

apply wwoods patch: hack to fix ppc ISO volume labels so yaboot doesn't flip out

    hack to fix ppc ISO volume labels so yaboot doesn't flip out

    blerg. yaboot freaks out if there's any slashes in its config, so we
    can't boot anything with non-ascii characters in the volume name. So we
    need to remove all non-ascii chars, and do it the same way lorax does
    it.

    This is why lorax and pungi shouldn't both be building bootable images.

yaboot is not in repo

You see the following during the build:

template command error in ppc.tmpl:
  runcmd /srv/pungi/test/work/Fedora/ppc64/installroot/usr/lib/yaboot/addnote /srv/pungi/test/rawhide/Fedora/ppc64/os/ppc/chrp/yaboot
  OSError: [Errno 2] No such file or directory

The solution is to install yaboot. However, yaboot is not in the rawhide repo!

yum install http://dl.fedoraproject.org/pub/fedora-secondary/releases/17/Fedora/ppc64/os/Packages/y/yaboot-1.3.17-2.fc16.ppc.rpm

(fixed) libdrm_nouveau.so.1()(64bit) is needed by xorg-x11-drv-nouveau- 1:0.0.16-34.20110720gitb806e3f.fc17.ppc64

I worked on http://fpaste.org/ua34/ . Karsten fixed it in the build simultaneously.

docbook-style-xsl-1.77.1-1.fc18 was tagged instead of docbook-style-xsl-1.77.2-1.fc18

At one time, ppc.koji looked like this:

NVR                                     Built by        Finished                State

docbook-style-xsl-1.77.1-2.fc18         karsten         2012-06-07 14:03:13     complete

It would be nice if we could figure out how this happened and prevent it in the future...

systemd.spec needs to depend on docbook-style-xsl >= 1.77.1-2

add the following to the spec file: BuildRequires: docbook-style-xsl >= 1.77.1-2

add "installpkg python-pyudev" to runtime-install.tmpl

You see the following during boot up:

don't delete ldconfig from glibc in runtime-cleanup.tmpl

It seems that the python code to find the udev library uses

$ ldconfig -p

So the fix would be to not delete it from the runtime image:

<mock-chroot>[root@bluebill ~]# vi /usr/share/lorax/runtime-cleanup.tmpl
...from
removefrom glibc /${libdir}/libthread* /${libdir}/rtkaio* /sbin/*
...to

systemd.spec Provides libudev

Now that you've included python-pyudev into the install image, you will see the following:

yum.Errors.YumRPMCheckError: [u'ERROR with transaction check vs depsolve:', 'libudev is needed by python-pyudev-0.15-1.fc18.noarch', u'Please report this error at https://bugzilla.redhat.com/enter_bug.cgi?product=Fedora&version=rawhide&component=yum']

The fix is to fix the systemd rpm to note that systemd-libs-186-1.fc18.ppc64.rpm needs to claim that it provides libudev.

[dwa] Not a bug, udev is being folded into systemd in f18

[hamzy] It looks like a bug to me.

pyanaconda/pyudev.py uses .0 version of libudev library

Anaconda searches for libudev.so.0. However, libudev is now libudev.so.1

Failed to start Network Manager

I see the following during startup:

[FAILED] Failed to start Network Manager.
         See 'systemctl status NetworkManager.service' for details.

When trying to look for logs, I could not find any. This seems like another problem to me.

Also, I noticed the following:

The following seems to fix it:

switch_root:/# sed -i -e 's/StandardError=null/StandardError=kmesg/' /sysroot/usr/lib/systemd/system/NetworkManager.service

ifconfig does not exist on install root

$ ip addr show

is equivalent. Also, other network tools like ping and nslookup are missing.
