I'm currently trying to do similar, but:
1. Parsing "fsck -C" output in systemd-fsck. All instances of
systemd-fsck send this progress status to plymouth, and let theme
decide how to display them on screen.
2. If user press e.g. 'C' to cancel a certain fsck job, then plymouth
will send SIGINT to corresponding instance of systemd-fsck.

This saves fsckd in "plymouth <-> fsckd <-> n * systemd-fsck".
