The goal of this project is to make Darwin more usable by providing an installation ISO, documentation, and add-on software. You are welcome to join #puredarwin on irc.freenode.net if you would like to join PureDarwin development and to add to this site.

MacFUSE

MacFUSE is a filesystem in userland. It runs well on PureDarwin and can be used to mount sshfs, ramdisk and other FUSE-based filesystems. It is, according to its maintainers, "The Easiest and Fastest Way to Create File Systems for Mac OS X" (and PureDarwin, one might add).

Installing MacFUSE

MacFUSE can be installed from the official MacFUSE.pkg (from the MacFUSE site) on PureDarwin with the following commands:

cd / ; gunzip -c "MacFUSE.pkg/Contents/Resources/10.5/MacFUSE Core.pkg/Contents/Archive.pax.gz"  | pax -r
chown -R root:wheel /Library/Filesystems/fusefs.fs/Support/fusefs.kext  
chmod -R 755 /Library/Filesystems/fusefs.fs/Support/fusefs.kext

Now MacFUSE is ready to use on PureDarwin.

sshfs

sshfs allows you to mount volumes over SSH.

Install the sshfs filesystem with
curl "http://macfuse.googlecode.com/svn/trunk/filesystems/sshfs/binary/sshfs-static-leopard" > /usr/sbin/mount_sshfs
chmod a+x /usr/sbin/mount_sshfs

Now we can mount a remote filesystem with
mkdir /Volumes/SSHVolume/
mount_sshfs user@some.host:/ /Volumes/SSHVolume/ -oauto_cache,reconnect,volname=SSHVolume

ramdisk

Status: functional in PureDarwin (Darwin 9)

ramdisk is, as its name implies, a ramdisk implemented in MacFUSE.
Install it with
svn co http://thebends.googlecode.com/svn/trunk/ramdisk/ ramdisk
cd ramdisk/
make
cp ramdisk /usr/sbin/mount_ramdisk
cd -
rm -rf ramdisk/

Now we can use the ramdisk command to create ramdisks:
mkdir /some/path
mount_ramdisk /some/path

Troubleshooting in building ramdisk and targetting Darwin 9

In case you plan to build it on Darwin 10, a couple of adjustements must be made.
Edit the Makefile and replace this line in order to be able to run it on Darwin 9:
CC = g++
by this line
CC = MACOSX_DEPLOYMENT_TARGET=10.5  g++

And this line
OPTS = -D_FILE_OFFSET_BITS=64 -D__FreeBSD__=10 -DFUSE_USE_VERSION=26
by this line
OPTS = -D_FILE_OFFSET_BITS=64 -D__FreeBSD__=10 -DFUSE_USE_VERSION=26 -arch i386

Problem: If you encounter:
file.cpp: In constructor 'ramdisk::File::File(ramdisk::Dir*, mode_t)':
file.cpp:17: error: 'assert' was not declared in this scope
cc1plus: warnings being treated as errors
or encounter
dir.cpp: In function 'void ramdisk::assertNoSubdirs(const std::string&)':
dir.cpp:11: error: 'assert' was not declared in this scope
[...]
dir.cpp:228: error: 'assert' was not declared in this scope
Solution: Simply add #include <assert.h> in file.h per example.

Problem: cc1plus: warnings being treated as errors
file.cpp: In member function 'virtual size_t ramdisk::File::Read(char*, size_t, off_t)':
file.cpp:26: warning: comparison between signed and unsigned integer expressions
Solution: Replace in file.cpp this line
  if (offset < len) {
by this line
  if ((size_t) offset < len) {

Then after a `make clean' and `make', everything should be fine and run on a PureDarwin release based on Darwin9:
MACOSX_DEPLOYMENT_TARGET=10.5 g++ -Wall -Werror -g -D_FILE_OFFSET_BITS=64 -D__FreeBSD__=10 -DFUSE_USE_VERSION=26 -c node.cpp
MACOSX_DEPLOYMENT_TARGET=10.5 g++ -Wall -Werror -g -D_FILE_OFFSET_BITS=64 -D__FreeBSD__=10 -DFUSE_USE_VERSION=26 -c file.cpp
MACOSX_DEPLOYMENT_TARGET=10.5 g++ -Wall -Werror -g -D_FILE_OFFSET_BITS=64 -D__FreeBSD__=10 -DFUSE_USE_VERSION=26 -c dir.cpp
MACOSX_DEPLOYMENT_TARGET=10.5 g++ -Wall -Werror -g -D_FILE_OFFSET_BITS=64 -D__FreeBSD__=10 -DFUSE_USE_VERSION=26 -c ramdisk.cpp
ar rcs libcommon.a node.o file.o dir.o ramdisk.o
MACOSX_DEPLOYMENT_TARGET=10.5 g++  -D_FILE_OFFSET_BITS=64 -D__FreeBSD__=10 -DFUSE_USE_VERSION=26 -o ramdisk main.cpp -L. -lcommon -lfuse
