A.7 CVS Tags

When obtaining or updating sources from cvs and CVSup a revision tag (reference to a date in time) must be specified. The following tags are available, each specifying different branches of FreeBSD at different points of time:

Note: The ports tree does not have any tag associated with it, it is always CURRENT.

The most common tags are:

HEAD

Symbolic name for the main line, or FreeBSD-CURRENT. Also the default when no revision is specified.

In CVSup, this tag is represented by a . (not punctuation, but a literal . character).

Note: In CVS, this is the default when no revision tag is specified. It is usually not a good idea to checkout or update to CURRENT sources on a STABLE machine, unless that is your intent.

RELENG_4

The line of development for FreeBSD-4.X, also known as FreeBSD-STABLE.

RELENG_4_4

The release branch for FreeBSD-4.4, used only for security advisories and other seriously critical fixes.

RELENG_4_3

The release branch for FreeBSD-4.3, used only for security advisories and other seriously critical fixes.

RELENG_3

The line of development for FreeBSD-3.X, also known as 3.X-STABLE.

RELENG_2_2

The line of development for FreeBSD-2.2.X, also known as 2.2-STABLE. This branch is mostly obsolete.
