How to format a partition inside of an img file?

Number of files per directory
I have a directory with about 100000 small files (each file is from 1-3 lines, each file is a text file). In size the directory isn’t very big (< 2GB).

Does the Linux kernel need a file system to run?
My opinion is yes, it does, because all useful exposure to the outside world (non-privileged processor mode) would first require a process running in the outside world. That would require a file system, even a temporary, in-RAM, file system.
Mounting multiple devices at a single mount point on Linux
Is there a way to mount multiple hard drives to a single mount point? Let’s say I run out of space on /home and decide to add an extra hard drive to the computer. How do I scale the space on a mount point? If I use RAID, can I add drives on the fly to increase space as I run out of them? Is there an alternative to using RAID if I am not interested in maintaining a high level of redundancy?
How do I find out what filesystem FUSE is using?
when I run mount, I can see my hard drive mount as fuseblk.
