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

Return the size in bytes of FILE, entering it if FILE is a directory.

Return an estimate of the size of the closure described by REFERENCE-GRAPHS, a list of reference-graph files.

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.

Populate the store under directory TARGET with the items specified in REFERENCE-GRAPHS, a list of reference-graph files. Items copied to TARGET maintain timestamps and permissions. When DEDUPLICATE? is true, deduplicate regular files as they are copied to TARGET.

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

This is a raw clone syscall wrapper that ensures no Guile thread will be spawned during execution of the child. `clone' is called with FLAGS. CHILD is a thunk to run in the child process. PARENT is procedure that accepts the child PID as argument. This is useful in many contexts, such as when calling `unshare' or async-unsafe procedures in the child when the parent process memory (CLONE_VM) or threads (CLONE_THREAD) are shared with it.

Get the extended attribute value for KEY on FILE.

Return the names of existing network interfaces. This is typically limited to interfaces that are currently up.

Use TERMIOS for the tty at FD. ACTIONS is one of of the values produced by 'tcsetattr-action'; see tcsetattr(3) for details.
