SAM/QFS file systems can not be mounted on a host with a read-only /usr file system.  \
See this code:

http://src.opensolaris.org/source/xref/samqfs/samqfs/src/fs/lib/mount.c#fsdLockName

It appears to me that the samfs "mount" utility is putting a read/write lock on \
/usr/lib/fs/samfs/sam-fsd to ensure only one copy of sam-fsd runs at a time.  That \
fails on a diskless client with a shared read-only /usr file system, or any host with \
                a read-only /usr file system.
