One of the longstanding strengths of Linux, and a key to its early success,
is its ability to interoperate with other systems. That interoperability
includes filesystems; Linux supports a wide range of filesystem types,
allowing it to mount filesystems created by many other operating systems.
Some of those filesystem implementations, though, are better maintained
than others; developers at both the kernel and distribution levels are
currently considering, again, how to minimize the security risks presented
by the others.
