Using Sheepdog
You need a "store" directory. I use /sheepdog formatted on /dev/sda5 as an ext4 partition.
mkfs.ext4 /dev/sda5
mkdir /sheepdog
tune2fs -l /dev/sda5 | grep "Filesystem UUID" | sed -e "s/^Filesystem UUID:\s*\(.*\)/UUID=\L\1\E\t\/sheepdog\text4\tdefaults,user_xattr\t1 3/" >> /etc/fstab
mount /sheepdog
mount
/dev/sda2 on / type ext3 (rw)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
tmpfs on /dev/shm type tmpfs (rw)
/dev/sda1 on /boot type ext3 (rw)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)
sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw)
/dev/sda5 on /sheepdog type ext4 (rw,user_xattr)
Note the (rw,user_xattr), this is important.
Now create the store.
