CI: No space left on device
On a local CI pipeline https://gitlab.freedesktop.org/rhabacker/dbus/pipelines/11126 most dbus builds are broken because of not enough space on device.
Not sure if that would solve the dedicated issue, but a disk usage check I did some weeks ago for dbus related packages showed me, that xmlto package needs about 1 GB device space. Multiplied with the number of builds (12) it occupies about 12GB, where xsltproc including docbook stylesheets requires only a few MB.
