BSD and Darwin derivatives

DragonFlyBSD 5.0 is the first release with preliminary boot support for HAMMER2, the project's new filesystem.

Preliminary HAMMER2 support has been released into the wild as-of the 5.0 release. This support is considered EXPERIMENTAL and should generally not yet be used for production machines and important data. The boot loader will support both UFS and HAMMER2 /boot. The installer will still use a UFS /boot even for a HAMMER2 installation because the /boot partition is typically very small and HAMMER2, like HAMMER1, does not instantly free space when files are deleted or replaced.

As an avid user of his DICE C compiler on the Amiga back in the old days, and a fan of DragonFlyBSD (with its own filesystem and the slab allocator) I think it's safe to say that Matthew Dillon is a genius.

Don't forget Blink, that linker saved me a lot of space on my Amiga disks.

Of course he is.

He was by far ahead of the time when implementing multicore support for FreeBSD, he implemented lightweight threads, usermode kernel on DragonFly, HAMMER and a lot of very technical stuff.

He does not get all the glory that deserves.
