JFYI, in order to try and solve a specific problem some 13 years go we envisioned (and also started as POC) a "OFS" or "Overlapped File System", where a filesystem contained also a (partial) image of itself (mappable as image): http://reboot.pro/topic/2887-boot-bartpe-as-img-from-hdd-with-grub4dos/ http://reboot.pro/topic/2887-boot-bartpe-as-img-from-hdd-wit... Basically a same file (same extents) was accessible both from the "outer" and from the "inner" filesystems. Then the idea was abandoned as another valid (and also simple/existing) solution to the actual problem was found through the use of "included in the standard" CDFS graft points: http://reboot.pro/topic/2887-boot-bartpe-as-img-from-hdd-with-grub4dos/?p=24374 http://reboot.pro/topic/2887-boot-bartpe-as-img-from-hdd-wit...
