Free BSD Jail

Free BSD Jail

The FreeBSD jail mechanism is an implementation of operating system-level virtualization that allows administrators to partition a FreeBSD-based computer system into several independent mini-systems called jails.

The need for the FreeBSD jails came from a small shared-environment hosting provider's (R&D Associates, Inc.'s owner, Derrick Woolworth), desire to establish a clean, clear-cut separation between their own services and those of their customers, mainly for security and ease of administration (jail(8)). Instead of adding a new layer of fine-grained configuration options, the solution adopted by Poul-Henning Kamp was to compartmentalize the system -- both its files and its resources -- in such a way that only the right people are given access to the right compartments.

Famous quotes containing the words free and/or jail:

    “Actually we are a vulgar, pushing mob whose passions are easily mobilized by demagogues, newspaper men, religious quacks, agitators and such like. To call this a society of free peoples is blasphemous. What have we to offer the world besides the superabundant loot which we recklessly plunder from the earth under the maniacal delusion that this insane activity represents progress and enlightenment?”
    —Henry Miller (1891–1980)

    “Brother, you can’t go to jail for what you’re thinking,”
    —Frank Loesser (1910–1969)
