* Resynchronise with Debian. Remaining changes: - Build only English (for now, until we figure out how to avoid trashing translations quite so badly with Ubuntu branding etc.). - Build only Ubuntu architectures (amd64, hppa, i386, ia64, lpia, powerpc, sparc). - Extensive (although possibly incomplete) Ubuntu branding, adjustments for our mirror layout, etc. - Add "Ubuntu and Debian" and "What is Ubuntu?" section, text borrowed from the Ubuntu web site. Disable the "What is Debian GNU/Linux?" section. - Direct installation reports to ubuntu-users for now. - Adjust various memory and disk space requirements. Talk about the default Ubuntu desktop and Ubuntu tasks rather than Debian tasks. - Document mounting /sys in various places. - Unset supports-floppy-boot for all our architectures. - Add a few more supports-floppy-boot and bootable-usb conditionals. - Document our root password and sudo arrangements. - Document netboot-style USB images. Still mention the hd-media images, but they're downplayed since many USB sticks are too small for a full Ubuntu ISO image. - Document Kickstart installations (currently only the basics, a reference to Red Hat's documentation, and the differences from Anaconda). - Update keyboard preseeding documentation for console-setup. - Update chroot-install guide for console-setup and language packs; add a bit more advice about installing grub. - Disable documentation of win32-loader. - Document new simplified partman preseeding. - Document mirror/udeb/components. - Document apt-setup/security_path. - Don't recommend passing http://archive.ubuntu.com/ubuntu to debootstrap. - Document partman/early_command. - Document pkgsel/update-policy. * Document that values for Kickstart's preseed command containing spaces must be quoted. * Document pkgsel/install-recommends. * Replace documentation on preseeding user-setup's encrypted private directory facility with documentation on preseeding its new home directory encryption facility (LP: #323174). * Improve examples of tasksel/first preseeding to avoid mentioning standard, which is installed by default. * Document partman-auto-lvm/guided_size.
