Created attachment 616043 [details] screenshot Description of problem: Today yum upgrade systemd form 188-3 to 191-2 version and my all Fedora 18 systems became unbootable. Every time boot process ended with message "segfault at 39 ip b7455447 sp bf926a68 error 4 in libc-2.16.so[b73d5000+1af000]" To recover I had to reinstall all Fedora 18 systems and after "yum update" do "yum downgrade systemd-libs systemd-sysv systemd libgudev1" immediately (before reboot). I don't know another way to recover system in this case. Be better if I could boot from LiveCD and attach unbootable system to anaconda for downgrade broken packages.
