I'm testing Nexenta in an effort to make Fuse for Solaris and my perl bindings play nice.

First, here is some info from machine:

root@solaris:~# uname -a
SunOS solaris 5.11 NexentaOS_20070402 i86pc i386 i86pc Solaris

Install dependencies

I installed just minimal Nexenta system, so if you installed desktop version, you might already have some of those packages. But, issuing this command anyway won't do any harm.

apt-get install mercurial gcc

Checkout source

hg clone ssh://anon@hg.opensolaris.org/hg/fuse/fusefs
hg clone ssh://anon@hg.opensolaris.org/hg/fuse/libfuse

Compile it

cd fusefs/kernel/
make
cd -

Install it

# root@solaris
cp fusefs/kernel/Sun-x86-Solaris/fuse /tmp/fuse
ln -s /tmp/fuse /usr/kernel/drv/fuse
echo '/name="fuse" parent="pseudo";/' > /usr/kernel/drv/fuse.conf
ln -s /devices/pseudo/fuse@0:0 /dev/fuse
rem_dev fuse
add_drv fuse
tail -3 /var/adm/messages
