FunionFS is an Union filesystem for the FUSE driver.
This program works only with the Fuse driver which is natively included since the 2.6.14 Linux kernel.
Above all, what is an Union filesystem?
It is a method used when one wants to manufacture LiveCD Linux such as Knoppix: support (CDROM) is only a read-only one.
The operating system, however, needs to write on this filesystem. The method consists in superimposing (Union) on the read only filesystem, a small size read-write one.
This filesystem (often stored in a RAMDISK) contains all the modifications made by OS on the CDROM content.
This method is often used for of Linux Stored in a PROM or a compressed file like in CRAMFS.
