Newer systemd is too smart, it detects the PIDs of the gettext calls and due to that a log lists libvirt-guests.sh with many different PIDs. Furthermore it struggles to collect the output in time, so it can be truncated and overall looks like: libvirt-guests.sh[37986]: Running guests on default URI: libvirt-guests.sh[37995]: Running guests on libvirt-guests.sh[37977]: R Gather the gettext result into a local variable and printing the value from libvirt-guests.sh itself fixes both issues.
