A.6 CVS Tags

When obtaining or updating sources from cvs and CVSup a revision tag (reference to a date in time) must be specified.

A revision tag refers to either a particular line of FreeBSD development, or a specific point in time. The first type are called ``branch tags'', the second type are called ``release tags''.

A.6.1 Branch Tags

All of these, with the exception of HEAD (which is always a valid tag), only apply to the src/ tree. The ports/, doc/, and www/ trees are not branched.

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_5_1

The release branch for FreeBSD-5.1, used only for security advisories and other seriously critical fixes.

RELENG_5_0

The release branch for FreeBSD-5.0, used only for security advisories and other seriously critical fixes.

RELENG_4

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

RELENG_4_8

The release branch for FreeBSD-4.8, used only for security advisories and other seriously critical fixes.

RELENG_4_7

The release branch for FreeBSD-4.7, used only for security advisories and other seriously critical fixes.

RELENG_4_6

The release branch for FreeBSD-4.6 and FreeBSD-4.6.2, used only for security advisories and other seriously critical fixes.

RELENG_4_5

The release branch for FreeBSD-4.5, used only for security advisories and other seriously critical fixes.

RELENG_4_4

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

RELENG_4_3

RELENG_3

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

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

A.6.2 Release Tags
