	11
	12	* MAYBE Add a substituter that uses the GNUnet DHT or [[http://libswift.org][libswift]]
	13
	14	Would be neat if binaries could be pushed to and pulled from the GNUnet DHT or
	15	rather libswift (since DHTs aren’t suited for large payloads). Guix users
	16	would sign their binaries, and define which binaries they trust.
	17
	18	Use UPnP and similar to traverse NAT, like ‘filegive’ does.
	19
	20	* user interface
	21	** add guile-ncurses interface
	22
	23	* extend <package>
	24	** add ‘recommends’ field
	25
	26	For instance, glibc, binutils, gcc, and ld-wrapper would recommend each other.
	27	‘guix package -i’ could ask interactively (?), or allow users to follow all or
	28	none of the recommendations.
	29
	30	** add a ‘user-environment-hook’
	31
	32	This should specify builder code to be run when building a user
	33	environment with ‘guix-package’. For instance, Texinfo’s hook would
	34	create a new ‘dir’.
	35
	36	** extend ‘propagated-build-inputs’ with support for multiple outputs
	37
	38	#+BEGIN_SRC scheme
	39	(outputs '("out" "include"))
	40	(propagated-build-inputs
	41	`(((("i1" ,p1 "o1")
	42	("i2" ,p2))
	43	=> "include")
	44	("i3" ,p3)))
	45	#+END_SRC
	46
	47	* synchronize non-GNU package descriptions with the [[http://directory.fsf.org][FSD]]
	48
	49	Meta-data for GNU packages, including descriptions and synopses, can be
	50	dumped from the FSD:
	51	http://directory.fsf.org/wiki?title=GNU/Export&action=purge .
	52	We could periodically synchronize with that.
	53
	54	* add a guildhall build system
	55
	56	The Guildhall is Guile’s packaging system. It should be easy to add a
	57	‘guildhall-build-system’ that does the right thing based on guildhall
	58	recipes.
	59
	60	* union
	61
	62	Support sophisticated collision handling when building a union: honor
	63	per-package priorities, etc.
	64
	65	* add GUIX_ALLOW_EXPENSIVE_TESTS
	66
	67	Tests that need to download stuff or otherwise take a long time would only be
	68	run when that is defined.
	69
	70	* guix build utils
	71	** MAYBE Change ‘ld-wrapper’ to add RPATH for libs passed by file name
	72
	73	** MAYBE Add equivalent to chrpath that uses [[https://gitorious.org/guile-dlhacks/guile-dlhacks/][guile-dlhacks]]
	74
	75	** MAYBE Add a hash-rewriting thing for deep dependency replacement without rebuild
	76
	77	See [[https://github.com/NixOS/nixpkgs/commit/d1662d715514e6ef9d3dc29f132f1b3d8e608a18][Shea Levy's `replace-dependency' in Nixpkgs]].
	78
	79	* distro
	80	** port to GNU/Hurd, aka. ‘i686-gnu’
	81
	82	Problems include that current glibc releases do not build on GNU/Hurd.
	83	In addition, there haven’t been stable releases of GNU Mach, MiG, and
	84	Hurd, which would be a pre-condition.
