IPFire, the hardened Linux distribution for firewall appliances, was recently updated to IPFire 2.11 Core update 61 and along with the enhancements, the developers announced that they are ending support for the Reiser4 filesystem. Rarely found in the wild, Reiser4 is an advanced filesystem, and sequel to ReiserFS, which offers an efficient journalling system, plugin support (for metadata or encryption), disk-layout optimisation and transaction support.
Its creator, Hans Reiser, was convicted of murdering his wife and since his incarceration development of the filesystem is no longer supported by the Linux kernel developers.
