"sudo rm /forcefsck" removes the file and should stop the file system
check at boot unless there is something wrong with your file system so
its marked dirty.

If I understand it right, when using a journaling file system it will
not be checked unless its marked dirty by the kernel, a check is
forced by /forcefsck, max-mount-count or interval-between-checks has
been reach.

You can check the current values max-mount-count and
interval-between-checks with "sudo tune2fs -l /dev/sda1". Replace sda1
with your partition to check.

See "man tune2fs" for more info and how to fine tune the file system
and when a check is forced.
