Obarun-install cannot be installed, with following looping error in the later stage of step 7: passwd - root password does not match.
This occurs in the build process after loading the AUR packages.
EDIT:
As mentioned before by Eric in another thread,
the problem gets solved by updating the glibc package using
sudo pacman -Sy glibc
(This might be worth adding to the installation procedure description at the Obarun wiki.)
