Speaking of which, how do I find out how the kfs is laid
out on disk?

/sys/src/cmd/disk/kfs/portdat.h has the data structures.
Look for `don't touch, this is the disk structure' warnings.
You could also follow the trace resulting from a check call.

`The Plan 9 File Server' (in /sys/doc/fs) describes how the pre-fossil
standalone file server stores data on disks. kfs is a slight variant
of the non-cached-worm file system. The main change I noticed when
adapting a private copy of kfs to read standalone file systems was
that struct Superb swaps the order of its members, a Super1 and an
Fbuf, to permit the size of the free list in Fbuf to vary with block
size, which can be chosen at run-time in kfs, but which is fixed at
compile-time in the standalone file server.

Hi,
Any advice on the "best" (I guess I mean simple and clean)
filesystem to look at as I try once again to teach
myself to write fileservers?
