[Samsung Galaxy Nexus] dechronic:
The fstab of the Nexus 5X has a lot of partitions, would that really cover it?

See the code below...

# Android fstab file.
#<src> <mnt_point> <type> <mnt_flags and options> <fs_mgr_flags>
# The filesystem that contains the filesystem checker binary (typically /system) cannot
# specify MF_CHECK, and must come before any filesystems that do specify MF_CHECK
