When emerging lufs-0.8.0 lufsd is not installed (only a link pointing from /usr/bin/lufsd to /sbin/mount.lufs and this file does not exist). It would also be nice to prepare a group for suid access to /usr/bin/lufsmnt so that allowed users can mount using lufsmount.
for the symlnk problem, you'll need to replace: dosym /sbin/mount.lufs /usr/bin/lufsd to: dodir /sbin dosym /usr/bin/lufsd /sbin/mount.lufs
solved with 0.8-r1
