A Look at the Filesystem Hierarchy Standard 3.0

Filed under
Linux

It was big news when the 3.0 kernel was released at the end of July, but as luck would have it, another fundamental piece of your average distribution is about to bump its own version number up to 3.0 as well: the filesystem hierarchy standard (FHS). If you're not sure exactly what that means or why you should care, don't worry. It's the distros that implement the FHS — when it goes well, all you know is that your system runs smoothly. But that doesn't mean there's nothing important hidden away in this new release.

The What Now?

The FHS defines the basic structure of a Unix-like operating system — what the directories are, what types of files and data belong in each, and so on. This is important for application developers (so that they know to create temporary files in /tmp/ rather than in the user's home directory, for instance), but it is also important for system administrators. Not only does FHS specify where the directories go, but it specifies important properties like which directories must be mounted read-only (critical for security) and which must be available at boot time (so that vital directories are on local disks not NFS mounts that won't be available early in the boot sequence).

Open source key to preserving human history, argues Vatican

Ammenti explained that, in order for the manuscripts to be readable, the Vatican Library opted for open source tools that do not require proprietary platforms, such as Microsoft Office, to be read. "We save it as a picture as it's longer life than a file. You don't rely on PowerPoint or Word. In 50 years they can still just look at it," he said. Read more

Open Source Router Connects US, Australia

The ONOS Project and partners said Wednesday they have demonstrated the real-world practicality of using a router with open source software to connect networks in Australia and the US. The test validates the vision of SDN, open source for carriers, as well as ON.Lab's ONOS network operating system, according to one of its coordinators. "SDN is about disaggregation of closed, proprietary boxes and separating of forwarding planes, control planes and applications," says Guru Parulkar, executive director and board member of ON.Lab , which coordinates ONOS development. The communications test between Australia and the US achieved just that, he says.
