Fedora 20 Released 147

sfcrazy writes "The Fedora Project has announced the release of Fedora 20, code named Heisenbug (release notes). Fedora 20 is dedicated to Seth Vidal, the lead developer of Yum and the Fedora update repository, who recently died in a road accident. Gnome is the default DE of Fedora, and so it is for Fedora 20. However unlike Ubuntu (where they had to create different distros for each DE) Fedora comes with KDE, XFCE, LXDE and MATE. You can install the DE of your choice on top of base Fedora."

    KDE Plasma Workspaces 4.11 and systemd, yes!

    I really like Fedora. Been using it since Fedora Core 1 (and Red Hat before that). It has been rock solid for me all these years, and it just keeps on improving.

    The new "systemd" internal plumbing system is a joy to use. "journalctl" is the finest new system tool I have seen for many years; it is really fast, and its superb autocompletion reduces typing to a minimum.

    "$ journalctl -F _SYSTEMD_UNIT" instantly show all systemd services that has ever written to the log file.

    "$ journalctl -b -1 -p err" filters the log file, so that only errors are shown (-p err) from the previous boot (-b -1, current boot is just "-b" etc.).

    A tremendous help for newbies who now doesn't need to learn 'cat', 'grep', 'less' and piping in order to do basic log file inspection.

    Besides improving my systemd skills, the next spare time project I will try on Fedora 20 is lightweight containers. They seems like a useful addition to full blown virtual guests.

    I noticed huge system slowdown with the introduction of journald. I noticed huge performance loss in reading and writing files on my hard drive. After some investigation I figured out that journald is the cause of all the slowness. After killing the process (multiple times) I figured out that the performance in writing and reading comes back to normal (used to know) speed. After investigating I figured out that after using the system that journald has created around 100-150mb of metafiles in /var/log/systemd and I am quite sure that I never had a software that generated so much logfile information.

    I read his comment just fine, my comment about CPU, as you would have understood if you had read carefully what I wrote, was a general observation that systemd-journald is a really fast lightweight daemon that doesn't consume much memory, or _even_ CPU time. (BTW, I can't fathom any scenario where a daemon does so much RW that it causes a system slowdown, without that daemon sucking up CPU time.)

    The OP may have experienced slowdown problems after his upgrade, but systemd-journald in it self wasn't the cause of it. Yes, I can imagine problems upgrading from eg. F17 to F19 without modifying the config files, since the systemd journal wasn't persistent in early Fedora versions, and running both systemd-journald and syslog may double the amount of disk writes.
