For the best end results, we might want to consider a collaberative work
on this. We could add a section to trunk (or a separate directory at the
top-level) specifically for this undertaking.
Suggested plan:
1) Describe the main differences between a typical LiveCD and a regular
system:
a) Target hardware is unknown
b) Even the root device name is unknown
c) The CD is read-only, and some scratch space is needed
d) The CD size is limited to 700 MB
e) The user should still be able to quickly configure everything he needs
2) For each problem, describe the method to solve it:
a) hotplug, udev, blacklist, ability to unload modules, X
autoconfiguration via detect-video.hotplug. Maybe mention the upcoming
(i.e. relevant for 2.6.15-rc5-mm1, but not for 2.6.15 yet) problem of
alternative drivers for IDE disks: "via82cxxx" vs "pata_via".
b) describe the initramfs, mention both klibc-based and C-based variants.
c) mention all three known approaches:
* the 6.0 way of not leaving the initramfs, drawbacks: must make sure
that the user will never want to change anything in /usr, e.g. aliases
for old bitmap fonts or fluxbox theme.
* unionfs, mention bugs
* dm, show both the equivalent shell script and the C API.
d) squashfs, zisofs, cloop
e) choice of applications: ban of the old core X font protocol, man vs
man-db, dialog-based configurators, etc.
