This TODO list can only touch on some larger issues, but there are a great
many open bugs on various components of the installer. See all bugs tagged
d-i in the BTS. Also, there are many unprocessed installation-reports.
Status for different parts of debian-installer. The numbers are
approximate (as in +/- 50%) and may change in any direction, at any
time.
[0%] Not begun
---------------------------------------------------------------------
- some architectures
hurd-i386 (we will ship w/o this)
sh (we will ship w/o this)
- support for non-free udebs
Driver disks are already supported, but that is not really
good enough for etch.
[30%] Might need large rewrites. Current implementation might
work by accident
---------------------------------------------------------------------
- persistent disk device names
With udev, the best approach, according to Md, is to use
the /dev/disk/ persistent devices which should always be
the same. Would need partman, bootloader installer,
probably other changes.
[60%] Needs some work, but does its grunt work
---------------------------------------------------------------------
- I18N
Mostly done, still filling in minor holes.
- translations
Varying languages translated to varying degrees.
http://people.debian.org/~seppy/d-i/translation-status.html
- boot loader installers (lilo, grub, etc)
Work, except for when they don't. See BTS.
- disk selector, partitioner
We have switched to partman everything except a couple of
subarches and s390.
- web site
http://www.debian.org/devel/debian-installer/
Could be better laid out, lacking some sections, other
parts are quite good.
- archive integration
No automatic propagation to testing.
No source propagation for udeb sources!
http://people.debian.org/~joeyh/d-i/testing-summary.html
- hw-detect
Working, but various issues with specific hardware.
- pcmcia support
Much improved, generally works now.
Automatic PCI resource range exclusion based on probing
still needed, work in progress.
- low memory support
Where "low" is 24-46 mb!
Works, but user must be careful to set up swap ASAP.
There is no sanity checking, and some bad failure modes.
More work needed for 16 mb installs.
- user documentation
Installation manual is up-to-date for i386.
Needs sanity checking for other architectures.
- developer documentation
We understand it, but it could be improved.
- integrate/document rescue mode support
Needs bootloader configuration (done on x86, sparc, ia64).
Needs easy ways to do common tasks like reinstalling a
bootloader (done for grub and yaboot).
- g-i
Working pretty well, still a few known bugs and UI issues.
- ppp support
Not as important for analog dialup, as for ISDN, pppoe.
pppoe-udeb works
- most architectures
i386
ia64
powerpc
mips
mipsel
m68k (some subarches)
- bvme floppies need root to build
alpha
sparc
- floppies need root to build
arm
hppa
amd64
s390
[90%] Single missing important feature or bug.
---------------------------------------------------------------------
- iso-scan
Works, but does not flag the disk the iso is mounted from
as unusable by the rest of the installer.
- netcfg
Working, pending rewrite for IPv6.
- localechooser
The perennial problem is how to order/present the list of
languages. Many complaints, but it works.
- base system installer
Improve kernel selection. Knowing about some kind of
preference order for kernels would be good. (Kamion)
- anna
Needs support for Release files.
- preseeding
Works pretty well.
Some things still cannot be preseeded. This is generally a
bug in the udeb's use of debconf.
[100%] Those shouldn't need to be touched any more
(famous last words)
---------------------------------------------------------------------
- udpkg
- cd installs
- net retriever
- cdrom retriever
- ethdetect
- cdebconf
- floppy retriever
- main-menu
- choose-mirror
- busybox integration
- install media build system
- kernel-package integration
- library reduction
- wireless support
- save-logs
- 2.6 support
- udev
Post-etch goals
================
- fix pkg-lists names to match images (joeyh)
- consistent indentation of all shell scripts
(with a style that minimises size on initrd! :-) (joeyh)
- 16 mb installs
- finish partman (anton)
- handle debian upgrades in partman (anton)
- fai integration (markos)
- use same device names in installer and installed
system (kamion)
- non-linux d-i (jbailey)
- moon-buggy udeb (cts@debian)
- britney and udebs
- fai disk config files in d-i (holger)
- low(er) mem (zboob)
- uml for testing d-i (anton)
- post reboot network configuration (kamion)
- real deb from archdetect udeb (luther)
- integrate selinux installation into the installer, for a painless
install (joeyh/manoj?)
- add a xen server task (joeyh)
- requires a way to install the xen kernel, which might
mean moving kernel etc package installation from the end
of base-installer to the end of pkgsel
Common problems and transitions
===============================
This is a list of common mistakes that need to be corrected throughout the
code base:
* All debconf commands that INPUT, GO, GET or SET questions should check
their return value. This is pure evil:
debconf->command(debconf, "GET", "mirror/suite", NULL); /* unchecked return code ! */
asprintf(&command, "foo %s", debconf->value);
system(command);
* cdebconf's debconfclient.h has a set of macros for calling debconf
(debconf_get() and so on)
These should perhaps be used consistently throughout the code for
clarity.
* udebs should not include md5sums files, or postrm, prerm, preinst
scripts. Linda will find these pretty well.
