Read the reference graph as produced by #:references-graphs from PORT and return it as a list of <store-info> records in topological order--i.e., leaves come first. IOW, store items in the resulting list can be registered in the order in which they appear.

The reference graph format consists of sequences of lines like this:

FILE DERIVER NUMBER-OF-REFERENCES REF1 ... REFN

It is meant as an internal format.

Copy ITEM, a store item, to the store under TARGET, the target root directory. When DEDUPLICATE? is true, deduplicate it within TARGET.

Fetch REVISION from URL into DIRECTORY. REVISION must be an integer, and a valid Subversion revision. Return #t on success, #f otherwise.

Stop using block special device DEVICE for swapping.

Load for eventual use of kexec(8) the Linux kernel from kernel-fd, its initial RAM disk from initrd-fd, with the given command-line (a string). Optionally, flags can be a bitwise or of the KEXEC_FILE_* constants.
