I'm thinking maybe local installs xubuntu with nomachine clients is the
best way to go. Has anybody tried something like that for their laptops?
Has there ever been any thought given to a LTSP "livecd" with wireless
support built into the kernel? That would be amazing for all the older
wireless devices that schools have invested in.
I would still suggest trying the method we used for the Bristol Wireless
machines. LTSP is meant for thin clients, whereas xubuntu will have the
overheads of a stand alone system, whilst not allowing you any of the new
local device access goodies that LTSP will give you.
The wireless-LTSP floppy was the basis for our old 2.4 kernel system, and
will boot over wireless. It can't run for LTSP 4.1+ because its a very
different environment. The new 2.6 kernel and initramfs images we use are
based on the very same idea. I didn't compile to wireless stuff because we
didn't need it, but there is absolutley no reason why you shouldn't do
that, and make a remote booting wireless image. If you want any details of
what I did, let me know. I have done a few minor updates on the wiki pages
mentioned previously in this thread.
A possible next project for me is to use LTSPFS to mount the remote hard
drives and replace the kernel images on the client drives, meaning I can
update them all from the server automagically.
The event in manchester on May 3rd was a great open source promotional
event, and the first outing for the new system, and I hope to do write up
from the Bristol Wireless stand point at some point. The machines we used
work well on the day after me installing the new 2.6 kernels on the
laptops in a rush the previous week.
I said to people that they should "try to break this, it's a new system
and we need to make it robust". There where a few debian related package
problems that we sorted out during the afternoon. The only other problem
was that Firefox kept crashing. This turned out to be that we didn't have
the NBD swap turned on. This is pretty amazing, in that the clients only
have 32mb RAM of their own! Any previous version of LTSP would have shown
symptoms a lot sooner. With NBD swap on, everything went fine.
