jgfs is a simple filesystem, written from scratch to imitate the overall design of FAT16 while excluding all of the DOS legacy nonsense that normally comes with a FAT filesystem. Its primary intended purpose is for use with the justix operating system project.

jgfs is no longer being actively developed, as jgfs2 is now the preferred filesystem of the justix operating system. The filesystem code itself is mostly stable, but hasn't been tested on a large scale.

This project uses Avery Pennarun's implementation of D. J. Bernstein's redo build system. For more information, see djb's redo page and apenwarr's redo implementation.

To build libjgfs, the FUSE program, and associated utilities, install redo and simply run redo all. To clean the project directory, run redo clean.

To build individual targets, run one of the following:

• redo lib: build the libjgfs library, bin/libjgfs.a
• redo fuse: build the FUSE program, bin/jgfs
• redo mkfs: build the mkfs utility, bin/mkjgfs
• redo fsck: build the fsck utility, bin/jgfsck

Make a new jgfs filesystem on a device or file:

bin/mkjgfs <device>

Mount the filesystem using FUSE:

bin/jgfs <device> <mountpoint>

• bin: contains the libjgfs library and utility binaries after a build
• doc: documentation related to the filesystem's development
• lib: source code for libjgfs
• src: source code for jgfs utilities and the FUSE program
• test: various scripts used for testing the filesystem
