Every time I install a package with dnf on Rawhide, it will hang for several seconds (perhaps 10-30), and then print out "warning: Unable to get systemd shutdown inhibition lock". Here's an example (look right after the first package is installed):


# rpm -q dnf
dnf-1.1.10-1.fc26.noarch
# dnf install /usr/bin/composer
