This is used as 'systemd-analyze show-config systemd/logind.conf', which will dump /etc/systemd/system/user@.service /etc/systemd/system/user@.service.d/*.conf /run/systemd/system/user@.service.d/*.conf /usr/local/lib/systemd/system/user@.service.d/*.conf /usr/lib/systemd/system/user@.service.d/*.conf The idea is to make it easy to dump the configuration using the same locations and order that systemd programs use themselves (including masking, in the right order, etc.). This is the generic variant that works with any configuration scheme that follows the same general rules: $ systemd-analyze cat-config systemd/system.conf $ systemd-analyze cat-config systemd/user.conf $ systemd-analyze cat-config systemd/logind.conf $ systemd-analyze cat-config systemd/sleep.conf $ systemd-analyze cat-config systemd/journald.conf $ systemd-analyze cat-config systemd/journal-remote.conf $ systemd-analyze cat-config systemd/journal-upload.conf $ systemd-analyze cat-config systemd/coredump.conf $ systemd-analyze cat-config systemd/resolved.conf $ systemd-analyze cat-config systemd/timesyncd.conf $ systemd-analyze cat-config udev/udev.conf
