Is there a way to have a permanent ramdisk which does not get automatically created at system start or user login?
Motivation:
I work with certain files every couple of weeks or so. I would like to create a ramdisk for those files and have the contents automatically saved at system shutdown. Since I do not work with the files daily, I do not want the ramdisk to be automatically created each time I start the system (which is daily). I want to create it on a as-needed-basis.
I don't see how this is possible because as soon as you assoicate an image file with the ram disk, it is automatically created.
