Without this, fsck would be re-run if any other service which pulls
in a target requiring one of the mounts was started after fsck was done
but before the initial transaction was done.

all other dependencies are in 3rd person. Change BindTo= accordingly to
BindsTo=.
Of course, the dependency is widely used, hence we parse the old name
too for compatibility.
The rule is that units that encapsulate our own code are prefixed with
"systemd-". Since the fsck units invoke our own code, hence add the
missing prefix. Since a long long time the fsck units didn't invoke the
naked fsck binaries anymore, and it is unlikely that this well ever
change. On the opposite: the code in systemd-fsck will probably get more
complex over time to handle fsck progress to plymouth forwarding.
Same for quotacheck (but not quotaon!)
