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.
Etienne.
