Actually, i've done an MSDOSFS (FAT-12 and FAT-16 only, though) for a
separate framework that's largely compatible with libsa (i lifted the
libsa FFS code for use with it, with minor mods, so... 8-), that
should be made freely available before too long...

and don't forget USTAR "fs" support, as well as things like gziped
binary support, and all those wonderful network load methods (do TFTP
and NFS count as "file systems")?  8-)

Further, it's not obvious why you'd even want them in the kernel,
since things like the load addresses are communicated nicely via the
ELF headers.

Actually, maybe i can imagine that you'd want notes there to provide
firmware/bootloader information that's not in the executable headers,
but I can't think of anything like that off-hand...
