What is the absolute path to the file that contains all the drives, hardware and network shares, that are mounted by the system during boot?

That is /etc/fstab (for its syntax see man fstab).

To be more precise it doesn't contain drives but filesystems to be mounted.

There is no single file that contains all drives, shares, etc. to be mounted at startup. /etc/fstab is where you're supposed to add these, but in practice, any method for running a command on startup as root can be used for mounting.

In the systemd world, the canonical way to mount anything at boot would be using systemd mounts. In systemd, even entries in fstab are converted to .mounts by the systemd-fstab-generator.

~ systemctl list-units --type=mount
UNIT                          LOAD   ACTIVE SUB     DESCRIPTION                                  
-.mount                       loaded active mounted Root Mount                                   
boot.mount                    loaded active mounted /boot                                        
dev-hugepages.mount           loaded active mounted Huge Pages File System                       
dev-mqueue.mount              loaded active mounted POSIX Message Queue File System     
...

~ systemctl cat -- -.mount
