Systemd Gets An Fsck Daemon/Service

The newest addition to systemd just a day after landing its new EFI boot manager is systemd-fsckd. This new addition was done by Ubuntu developers.

There's now a systemd-fsck service and systemd-fsckd daemon. This isn't about systemd working towards its own file-system or anything of that sort, but rather is just for better fsck integration so systemd can relay the information, e.g. to the Plymouth boot splash screen. As explained by the commit, "Add systemd-fsckd multiplexer which accepts multiple systemd-fsck instances to connect to it and sends progress report. systemd-fsckd then computes and writes to /dev/console the number of devices currently being checked and the minimum fsck progress. This will be used for interactive progress report and cancelling in plymouth."

The systemd fsckd work was led by Didier Roche and Martin Pitt of Canonical. This work is being done as part of Ubuntu/Debian's work toward systemd replacing Upstart in Ubuntu.
