    For FreeBSD, HEAD (tip of the cvs tree) is -CURRENT, RELENG_M is a
    -STABLE branch (i.e. RELENG_4 is FreeBSD-4-STABLE, and RELENG_3 is
    FreeBSD-3-STABLE), and RELENG_M_m is a security/ciritcal branch (i.e.
    RELENG_4_8 or RELENG_5_1 will only get critical fixes applied to them).

    When the time comes for 4.9 to be released, RELENG_4_9 will be branched
    off RELENG_4 a couple weeks before release, and then the
    RELENG_4_9_0_RELEASE tag will be laid on that branch, which represents
    what gets burned onto CDs.

    Correct. If you want -STABLE, you'll want the RELENG_4 branch, since
    5.x has not been marked stable yet.
    http://www.freebsd.org/handbook/cvs-tags.html has a good summary of all
    the branches and what their purpose is. If you want a stable-ish 5.x
    tree, RELENG_5_1 is probably a better choice than RELENG_5_0. Or scan
    the -current mailinglist archives, find a week where there aren't any
    "-CURRENT is broken!!" threads, and checkout a copy of HEAD from that
    date :)

    http://www.freebsd.org/releng/ lists all the branches and their current
    status (open/frozen).

    In general, HEAD is okay, and if it isn't, it's usually only a single
    component (say groff, or a kernel module) that's broken, and that's
    fixed quickly.
