• I am mostly working on Red Hat Enterprise Linux with most of the development work first going into Fedora Core.
• There is a FedoraProject Wiki for most of the changes going into Fedora and its fast Linux development path.
• Fedora Extras (FE) is an even more open project ontop of Fedora Core (FC).
• Most wiki content is at http://www.jur-linux.org/wiki/.
• git and mercurial are two very modern source code management tools. They allow offline operation, scalable and fast setups and are both key for Open Source development. To follow the Fedora Core development projects, a cronjob is downloading every 4 hours the newest data from upstream projects and is also migrating cvs projects into git repositories. You can then mirror all that data onto your laptop for offline work or use the gitweb interface to quickly check the current status in case FC-development has broken your setup and you want to help fixing bugs.
  These are the locally mirrored git repositories and also locally mirrored hg/mercurial repositories.
  Access to the repository data is also available at git-data and hg-data and also via rsync://www.jur-linux.org/.
• PyRPM - python rpm project
• misc collection of files
• additional source rpm packages
  Use the following entry as /etc/yum.repos.d/addons.conf for FC4 or for FC-development:

  [addons] name=collection of addons baseurl=http://www.jur-linux.org/rpms/addons

  And if you have Fedora Core development installed you can add the following lines in addition to the above:

  [addons-development] name=addons for FC-development baseurl=http://www.jur-linux.org/rpms/addons-development

  For FC4 use the following entry as /etc/yum.repos.d/fc-updates.conf to update a few packages to newer versions and/or add a few bug-fixes:

  [fc-updates] name=updates for Fedora Core baseurl=http://www.jur-linux.org/rpms/fc-updates/$releasever/$basearch

• Download of ISO/DVD images of Fedora Core 5, also available via rsync://www.jur-linux.org/download/.
• first start to collect unofficial infos about the Kindergarten/Hort of my kids
• Old start to collect a few links, should be all rather obsolete by now.

• Infos about my 1und1 root-server setup.

Linux tipps and tricks

• If you want to install the Fedora Core development tree, you should first check if the dependencies look somewhat sane. Either look at the fedora-devel-list@redhat.com mailinglist archives to see the daily mail about the status or check it yourself with:

  ./pyrpm.py --noverify --checkdeps --nodigest --nopayload --small --arch=i686 --fileconflicts -v /mirror/fedora/development/i386/os/Fedora/RPMS

• Sometimes it helps to add the kernel parameter selinux=0 to get a working installation. You can add this at the syslinux prompt for the boot/install CD or to your grub configuration at /boot/grub/grub.conf.
• qemu-install.txt script to install and run Fedora Core 4 via a text console (serial port within qemu). Best used together with screen to install/run virtuell qemu machines.
• If you are using qemu or VMware, you should add a clock=pit to your kernel parameters. Or try clock=pmtmr or the qemu option -no-tsc which is added into my qemu rpm package. FC-development and newer kernels use clocksource instead of clock.
• Add the following lines into /etc/sysctl.conf to get better qemu, mplayer and VMware quality:

  # for better qemu/mplayer/VMware support dev.rtc.max-user-freq = 1024

• If you do not need IPv6, you can disable it via "install ipv6 /bin/true" in /etc/modprobe.conf. Fedora Core 6 and newer also have IPv6 support during the installation and you can turn that off via the "noipv6" option.
• If your installation hangs, you might want to try booting with noapic and/or acpi=off. Sometimes pci=noacpi, which is less invasive than acpi=off, is sufficient.
• FC-development has a few basic commands like head/tail/sort which do not work by default with options like +1 any more. Either set the environment export _POSIX2_VERSION=199209 or add the patch from past coreutils releases again into the newest FC-development package to also use older options by default (coreutils-5.0-allow_old_options.patch).
• Set export MOZ_DISABLE_PANGO=1 to disable pango for mozilla firefox. Fedora Core 5 and newer has this optimized already.
