[arch-general] new AIF release

[Dieter Plaetinck]

Hello Arch devs and users,
here is my holidays present for you: AIF alpha-0.6 !

* Changes since alpha 0.5:
- fully reworked disk subsystem
  - support for lvm and dm_crypt
  - Autoprepare looks exactly the same (ui-wise)
  - Manual mode UI is entirely reworked and has a general editor (see 
screens)
  - Unified, more flexible/reusable backend code for partitioning, 
making filesystems and mounting them.  Uses structured file formats for 
defining partitions and filesystems
  - Rollback functionality: when something failed while processing, or 
user changes his mind afterwards, you can do a rollback (things like 
umount, lvremove etc are done automatically in the correct order) and 
start over/retry
- fully decoupled UI (dia/cli):
  - there are now generic, transparent functions for asking 
dates,numbers,strings,checklist,.. etc with an implementation in both 
ncurses (dialog) and cli.
  - all code now uses these functions, making the codebase much cleaner. 
(look at the code for autoprepare for instance)
  - with a simple command line flag you can toggle between running the 
program in cli or dialog mode.
- support for commandline args
  - /arch/aif -p interactive -d     # runs the interactive profile with 
debugging enabled
  - /arch/aif -p interactive -i cli # runs the interactive profile in 
CLI mode.
- updated howto for using AUR packages
- replaced all refs to previous name (fifa) to aif.
- enabled date/time setting
- a massive amount of bugfixes
- a lot of code cleanups

* Screenshots
- AIF manual filesystems, here showing a setup with /dev/sda3 containing 
a dm_crypt, containing /, and /dev/sda3 containing an LVM setup with 1 
LV for /home

everything

- a CLI shot where the partitions/filesystems of the autoprepare just 
have been processed

* Usability
I tested the installer personally in virtualbox in different scenarios 
(ftp & cdrom based, autoprepare, manually with normal disk layout,/ on 
lvm, dm_crypt,.. ), and all produced working installations.
Although I often need to fix bugs after testing a specific scenario,  I 
don't re-test all scenarios each time.  YMMV
Note that the installer doesn't automatically add the lvm2/encrypt 
modules to mkinitcpio yet, and doesn't add the right string for 
lvm/dm_crypt in grubs menu.lst yet.

There are some known issues (which are not critical, just avoid them or 
live with them).  Here are the biggest ones (for more, see TODO)
- don't remove lvm LV's if you have more then one in one lvm VG.  So 
think before you create :-)
- make the correct devicemapper devices directly because they are not 
cleaned up correctly if you remove them again
- keyboard and timezone settings from installer don't go into target 
systems config
- long selections (eg packages) are very cumbersome to do in CLI mode.
- rollback of dm_crypt partitions doesn't work yet

* How?
http://github.com/Dieterbe/aif/tree/master/HOWTO

Use package aif-git from AUR.
Even though I tag releases in git, I don't build packages for them.
I now use the master branch as "stable" branch where I pull in code from 
the experimental branch after it has been tested.
So the master branch (package aif-git) always contains the latest, 
stable code.

Use "/arch/aif -p interactive -d" (the interactive procedure is the port 
of /arch/setup)

Have fun,
Dieter
