| Discussion summary

apt bugs - repository format documentation
	http://wiki.debian.org/RepositoryFormat
	field in the derivs census with tool info
	most distros use reprepro apt-ftparchive

blends stuff
	jessie tasksel plans to allow installing blends from the installer

secure boot plans?
	ubuntu has an implementation
	implementation in Debian was blocked on key generation and dak work; both making progress this DebConf, should see results within a month or two
	reproducible builds of shim and integration of MS sigs
	MS sigs are a cost for MS :)
	need signed kernel modules - openafs & dkms

things needed from Debian
	hLinux - foundation for openstack cloud
		commitment towards opening most of the things
		following the rebranding rules and not breaking things - followup
	Grml - sysadmin tool
		configuration file modifications
			openssh for example
			config-package-dev is totally awesome
			need more support for .d directories - please ask upstream

dpkg-vendor
	how many derivatives to integrate?
	probably not many variants
	conffiles in /etc/dpkg/origins/ with parent metadata enables --is and --derives-from queries during the build
	jessie popcon reports the default distro

initramfs - alternative tools?
	broken on some arches - booting without initramfs
	patches http://dex.alioth.debian.org/census/patches/i/initramfs-tools/

installers? d-i, ubiquity?
	Ubuntu - ubiquity for most things, d-i still in use for non-trivial automated deployments
	SteamOS - customised preseeded d-i and image based installers
	grub issue with where to install (Offtopic note: This was also pointed out in installer-cd 's gobby)
	hLinux - creates an image using d-i
	scripts to remove stuff - strategies: debian-live, cloud-init, just create exact images, don't install ssh
	debootstrap/multistrap for multi-repos and stripping. preinst stuff
	declarative config for files to remove at first boot
	entropy is low at first boot, don't generate keys then (regression in systemd, bug #pending, filed)
	option to specify not to generate system-specific files and run postinsts later
	https://wiki.debian.org/ReproducibleInstalls
		man-db - timestamps in the databases important optimisation, but could be done by touching the dbs to the right mtime instead
			[pabs] file a bug
	hostname leaking into the image/install
		checking two runs of an install with different hostnames
		containers namespacing?
		policy about not copying the hostname around? libnss-myhostname

systemd & derivs?
	tanglu - switched
	Ubuntu switching, not done yet
	hLinux experimenting with it
	Tails - kexec issues

| Food for thought

Redesigning Debian as a metadistro. (Longer explanation at http://deb.li/GXpG). So a summary will be: Encourage Debian derivatives officially. At the same time setup or develop some tools to make derivatives work more direct (Live CDs, Installer, Archive) and document how they have to use it. Finally make sure that these same tools make it far more easy than today for derivatives to contribute their own customisations and packages back to Debian.
