Roll back to the previous generation of PROFILE. Return the number of the generation that was current before switching and the new generation number.

Return the entries of MANIFEST along with their propagated inputs, recursively.

Return the default properties of a manifest entry for PACKAGE.

Add a list of manifest ENTRIES to MANIFEST and return new manifest. Remove MANIFEST entries that have the same name and output as ENTRIES.

Return a derivation that builds a single-file bundle containing the CA certificates in the /etc/ssl/certs sub-directories of the packages in MANIFEST. Single-file bundles are required by programs such as Git and Lynx.

Return a list of manifest entries, one for each item listed in PACKAGES. Elements of PACKAGES can be either package objects or package/string tuples denoting a specific output of a package. PROPERTIES is a procedure taking one argument and returning an alist.

Return a derivation that builds a profile (aka. 'user environment') with the given MANIFEST. The profile includes additional derivations returned by the monadic procedures listed in HOOKS--such as an Info 'dir' file, etc. Unless ALLOW-COLLISIONS? is true, a '&profile-collision-error' is raised if entries in MANIFEST collide (for instance if there are two same-name packages with a different version number.) Unless ALLOW-UNSUPPORTED-PACKAGES? is true or TARGET is set, raise an error if MANIFEST contains a package that does not support SYSTEM.

When LOCALES? is true, the build is performed under a UTF-8 locale.

When RELATIVE-SYMLINKS? is true, use relative file names for symlink targets. This is one of the things to do for the result to be relocatable.

When TARGET is true, it must be a GNU triplet, and the packages in MANIFEST are cross-built for TARGET.

Return the PROFILE's manifest.
