'emelie' is for any Plan 9 machine with supported hardware (excluding the SONY jukebox), and will make an object '9emeliefs' and use a 16KB block size and 32-bit file sizes. choline is similar, but with conf.nfile cranked up. fs uses a 4KB block size and 32-bit file sizes, rereads all blocks written to the WORM, and is configured with more `large message' buffers than is usual (for gigabit Ethernet). fs64 is similar but uses an 8KB block size and 64-bit file sizes, offsets and block numbers, and consequently can only serve 9P2000, not 9P1. 9netics32.16k is like fs, but uses a 16KB block size and does not reread blocks written to the WORM. 9netics64.8k is like fs64, but uses an 8KB block size and does not reread blocks written to the WORM. To spin-off a new version to play with, say 'test': cd /sys/src/cmd/cwfs mkdir test for (f in mkfile dat.h conf.c) sed '1s/emelie/test/' emelie/$f >test/$f and hack as appropriate. The primary choices are block size and 32- or 64-bit sizes (in dat.h), and various configuration tweaks and choice of 9P variants to serve (in conf.c).
