OpenNebula

Hi,

It seems there is a problem with the postun scriptlets in the rpm. It suppose that the service is running, and if it's not the case, fails to run this postun script. Therefor, yum/rpm is not able to uninstall this package.

The best practice for RPM scriptlet for that specific case is to return true:

    preuninstall scriptlet (using /bin/sh):
    if [ $1 = 0 ]; then
        /sbin/service opennebula stop >/dev/null
        /sbin/chkconfig --del opennebula >/dev/null
    fi

to

    preuninstall scriptlet (using /bin/sh):
    if [ $1 = 0 ]; then
          /sbin/service opennebula stop >/dev/null ||:
          /sbin/chkconfig --del opennebula >/dev/null
    fi

Btw I can't find the spec files in the git repos?
