Marshall Kirk McKusick (b. January 19, 1954 in Wilmington, Delaware) is a computer scientist, famous for his extensive work on BSD, from the 1980s to FreeBSD in the present day. He was president of the USENIX Association from 1990 to 1992 and again from 2002 to 2004, and still serves on the board. He is also on the editorial board of [ACM Queue Magazine]. He is known to friends and colleagues as "Kirk".
McKusick received his B.S. in electrical engineering from Cornell University, and his Master's degree in business administration and Ph.D. in computer science from the University of California, Berkeley.
He lives in California with Eric Allman, his domestic partner since graduate school. McKusick is an avid wine collector and the temperature and vital statistics of his house and wine cellar are available on the web from his homepage.
BSD
Kirk started with BSD by virtue of the fact that he shared an office at Berkeley with Bill Joy, who in essence spearheaded the beginnings of the BSD system. (source: [BSDTalk interview with Kirk McKusick]).
Some of McKusick's largest contributions to BSD have been to the file system. He helped design the original Berkeley Fast File System (FFS). More recently, he implemented soft updates, a new approach to maintaining disk integrity after a crash or power outage, in FFS, and a revised version of UFS known as "UFS2".
He was also primarily responsible for creating the complementary features of filesystem snapshots and background fsck (file system check and repair), which both integrate closely with soft updates. After the filesystem snapshot, the filesystem can be brought up immediately after a power outage, and fsck can run as a background process.
The Design and Implementation series of books are regarded as very high quality works in computer science. They have been strongly influential in the development of the BSD descendants and have contributed to their cohesive and well-thought-out nature.
