A Fuchsia package is one or more collections of files that provide one or more programs, components or services for a Fuchsia system. A Fuchsia package is a term representing a unit of distribution, though unlike many other package systems, that unit is composed of parts.
meta.far
A package as "built" by the pm tool is a tree of zero or more
content-addressed items. At the top of this tree is a Fuchsia Archive
commonly named meta.far.
meta.far contains the meta/ directory provided as an input to a package
build, and contains at minimum two files, described below. It can also
contain additional metadata items, such as component manifests.
- meta/package
- The package identity file is a JSON file containing the name and version of
- the package.
- meta/contents
- The contents file, typically produced automatically by
pm update(an - implied step in
pm build) maps the user-facing file names of a package, - to the content-addresses (Merkle Root)
- of those files.
The format of meta/package and meta/contents are considered private
specification at this time, and may be subject to change.
Additional Metadata Items
It is common to store some additional files in the meta directory of a
package, for example Component Manifests.
