It prevents the Bourne Shell to pass it's compliance test.
POSIX requires builtin commands to fail in case of a failing I/O redirection without exiting the shell.
Since POSIX does not permit directories to be opened for writing, >/ is used to run the test.

rootfs just seems to be very nice to everyone (http://cgit.haiku-os.org/haiku/tree/src/system/kernel/fs/rootfs.cpp#n586).
Is this actually a problem for anything, or just something you accidentally stumbled upon?
