many thanks to you for bundling hopefully modified libraries [1] in your open source projects. You can be almost sure that your otherwise useful application won't be part of a major Linux distribution like Fedora or Debian.
Your package maintainers
PS: There are definitely more reasons that complicate the way to a distribution like e.g. imprecise licensing, but the bundled libraries one made me really angry during the weekend. And it was in a such nice application ...
PS2: The article may contain irony, cynicism and others
- install new fedora-release package
- yum update glibc, because there was some dependency error reported by rpm
- yum update - 1.6G in ~2200 packages were downloaded, few packages had to be removed from the F14, they were causing broken dependencies
- grub2 was manually installed using the steps from http://fedoraproject.org/wiki/Featu
res/Grub2#How_To_Test - reboot, in fact the power switch had to be pressed because the soft way was not possible due the change from upstart to systemd
And voila, Fedora 16 is booting and running. During the Fedora release upgrade I've also switched from Gnome to XFCE desktop environment. Bye bye Gnome, it has been nice years, but Gnome 3 is incompatible with how I do my work.
The visual representation of the progress is here
The required steps will be described here (I'm retrieving them from my memory and .bash_history, so I hope they are complete and correct)
- create /etc/yum.repos.d/fedora.repo with this content
[fedora] name=Fedora baseurl=http://ppc.koji.fedoraproject.org/mash/branched/ppc64/os/ gpgcheck=0 enabled=0
- prepare a logical volume (I use Linux as the existing volume group) and mount it
lvcreate -L 20G -n Fedora Linux mkfs.ext2 /dev/Linux/Fedora mount /dev/Linux/Fedora /mnt
- install the really important packages
yum --disablerepo=* --enablerepo=fedora --installroot=/mnt install openssh-server yum
- remove root's password from /mnt/etc/shadow (or you can copy an existing encrypted password there), the first line should be something like
root::14858:0:99999:7:::
- add a minimal /etc/fstab
/dev/mapper/Linux-Fedora / ext4 defaults 1 1 tmpfs /dev/shm tmpfs defaults 0 0 devpts /dev/pts devpts gid=5,mode=620 0 0 sysfs /sys sysfs defaults 0 0 proc /proc proc defaults 0 0
- install the F-15 kernel on the host system
rpm -ivh --nodeps kernel-2.6.38.4-19.kh.fc15.ppc64.rpm - copy the modules from the host to the new Fedora system
cp -a /lib/modules/2.6.38.4-19.kh.fc15.ppc64 /mnt/lib/modules/ - point the F-15 kernel to new root filesystem - replace the original value for root= with /dev/Linux/Fedora in /etc/yaboot.conf
- disable SELinux by adding selinux=0 in the kernel entry in /etc/yaboot.conf, could be probably enabled again when the policy package is installed
The /boot filesystem lives on a separate partition (/dev/sda2 on my system) and it can be shared between the host and the newly installed Fedora
If you want network to up in new Fedora system, do these 2 additional steps
- install NetworkManager with
yum --nogpgcheck --disablerepo=* --enablerepo=fedora --installroot=/mnt install NetworkManager
or add NetworkManager to the yum command line above - copy the network interface config file from the host to the new Fedora
cp /etc/sysconfig/network-scripts/ifcfg-eth0 /mnt/etc/sysconfig/network-scripts/ cp /etc/sysconfig/network /mnt/etc/sysconfig/
Now you can reboot and on the yaboot prompt select the Fedora 15 kernel. You should see a Fedora welcome message after a bunch of systemd messages on the console at the end. If not try pressing Enter. If you installed also the NetworkManager then the network should also up, so you can try connecting with ssh too.
If you have more questions, please catch us on the #fedora-ppc IRC channel on Freenode or on the fedora-ppc mailing list.
EDIT 2011/08/31:
when doing the install from F-12 you should get a kernel >= 2.6.32 first (the glibc in F>=14 requires it) otherwise you will get "kernel too old" messages and probably some failures during the install
The U-Boot bootloader in the Efika has a nice feature built in. It supports booting user supplied OS image when a simple rule is followed = put the kernel image on first partition (use uImage as filename) and the root filesystem on the second partition. Now press the power button and voila, Fedora 13 XFCE desktop is there (click for full-size image) :-)
Some details about the setup:
- kernel is 2.6.31.12.3-ER1-efikamx from my archive, a newer one should work too, but I've spent too much time with latest kernel and faulty SD card ...
- F13 beta root filesystem with the XFCE packages installed manually, the repository doesn't include information about package groups (like the "XFCE desktop" or "GNOME desktop" groups), so they were installed individually. To be precise the top-level packages were installed and the rest was brought in as dependencies. Full package list is here
PS: I think I will buy the Smartbook from Genesi Europe very soon, there is even an option to get a replacement keyboard with Czech layout.
