Messed up F18->F19b upgrade with yum

[Andrii Bordunov]

Hi all. Got an interesting problem while doing F18->F19b upgrade with
yum distro-sync.
Conseqeuences are already solved, I'm just curious about it and maybe
it will provide some info to someone.

The problem is that yum just freezed in the middle of update and I had
to kill -9 it. Might be related to systemd cgroups point[1], but in
this case warning should be more detailed and strong, as for me.

The failed operation[2] was lauched at night under screen(1) with PWD=/root
At the morning I saw it frozen on this (taken from the screen log):

    Updating   : libreport-python-2.1.4-5.fc19.x86_64       769/3087
    Updating   : abrt-libs-2.1.4-3.fc19.x86_64              770/3087
    cat: /var/tmp/abrt/oops-2013-02-28-19:49:04-663-1/uid: No such
file or directory
    Updating   : abrt-2.1.4-3.fc19.x86_64                   771/3087

Machine state seemed ok—I was able to login on VT3 and kill yum with
SIGKILL. All another methods didn't help: ctrl+c, ctrl+z, SIGTERM,
SIGHUP, SIGINT,..
Yum process state was "interruptible sleep" in ps(1).
Related syslog snippet is below[3].

Before this a similar upgrade on another machine was performed fine.
