+modloop initd scripts allows firmwares to be loaded from boot medias' /firmware directory.
+This is helpful, but that means having to know all the firmwares for the given device and
+ copying onto /firmware folder. This can be improved if a script can figure all the needed
+ ones and create/print a list.
+
+Feature asked below modifies the exiting modloop overlay functionalities and copys' /firmware
+ onto it. Now, I only need to have other needed firmwares in /firmware directory.
+
+I am not aware if modloop overlay is meant for to be used in some other way, having
+ it documented would be nice.
+
+Hope this explains the need. The idea is some-what implemented in POC scripts
+ (find attached below)
