creating fat 'thin' clients with ltsp

[David Van Assche]

Hi Jim,
   The one thing to remember is that the ltsp-client-core part of the
startup process does certain things like auto-configure X, create an
automated fstab with detected devices, and so on. One would have to look at
ltsp-client-core and ltsp-client-setup to understand exactly what it does at
setup and startup. But I believe it would be better to explode the necessary
items in the thin client chroot after an ltsp-build-client. I believe the
ltsp startup parts are still quite valuable and will allow for upgrades
without breaking anything, which is what I have tried to do in the wiki, by
utilising elements like XF86CONFIG= and RC_FILENN= in lts.conf.

   I know Ogra is looking into creating a script that does all of this
automatically, but it is still a ways off (hardy+1 maybe?), but if you find
it possible to do it the way you mentioned, please document it and add to
the wiki... There are invariably many ways to achieve the same end result,
but working with the ltsp structure so we can upgrade the environments as
and when we need to will be important.
