Yes. Look at this test. I used normal file loop-mounted. See attached script. Here are some results: ---------------------------------------- tmpfs on /un/write type tmpfs (rw) /un/testfs on /un/rdonly type reiserfs (ro,loop=/dev/loop1) unionfs on /un/union type unionfs (rw,dirs=/un/write=rw:/un/rdonly=ro) touch: cannot touch `/un/union/new_file': Read-only file system ---------------------------------------- tmpfs on /un/write type tmpfs (rw) /un/testfs on /un/rdonly type xfs (ro,loop=/dev/loop1) unionfs on /un/union type unionfs (rw,dirs=/un/write=rw:/un/rdonly=ro) touch: cannot touch `/un/union/new_file': Read-only file system ---------------------------------------- tmpfs on /un/write type tmpfs (rw) /un/testfs on /un/rdonly type ext2 (ro,loop=/dev/loop1) unionfs on /un/union type unionfs (rw,dirs=/un/write=rw:/un/rdonly=ro) ls /un/union lost+found new_file ---------------------------------------- tmpfs on /un/write type tmpfs (rw) /un/testfs on /un/rdonly type ext3 (ro,loop=/dev/loop1) unionfs on /un/union type unionfs (rw,dirs=/un/write=rw:/un/rdonly=ro) ls /un/union lost+found new_file ---------------------------------------- > > I use unionfs-1.1.1. > > Can you help me? > > You should try to use the latest 1.1 release or CVS.
