# JFFS2 file system
# If used with binwalk's smart signature feature (on by default, -S to disable)
# this signature can potentially lead to missing some JFFS2 file systems if there
# are multiple JFFS2 file systems in a target file and there are no other identified
# files in between the JFFS2 file systems. This is an unlikely scenario however, and
# the below signatures are much improved in terms of readability and accuracy in the
# vast majority of real world scenarios.
