What I would like is to treat completely differently writing to FAT (writing to a removeable drive) which need a complete "mount", and just reading quickly a file (a standard use of removeable devices). Basically, to read you would not need to mount the partition, just read /readfs/fd1 which uses two or three functions accessing /dev/fd1 in raw mode to read the filesystem descriptor and the root directory. Same for /readfs/cdrom and /readfs/sda4 (USB drive). The only cache would be the one provided by /dev/fd1 - a kind of mount read-only at each file opening. This system would be disabled if the partition is already mounted read/write somewhere - but as long as you do not try to write to a removeable disk you can extract it at any time. The two or three function I am talking of are located in Gujin "fs.c" file to access read-only FAT12/16/32, EXT2/3 and ISOFS ( http://gujin.org ). Just few kilobytes - and some source modifications for that use.
