Also, in the kernel config file in /XO-alt-distro/kernel/2.6.25.15-XOaltF9-1
That's the main thing that worries me - the kernel. I'd like to use a standard F9 kernel -- when I talk about "backporting cleverness", it's about applying some fixes that IIRC Jeremy Katz applied to the initrd that F10 carries.
We need a standard Fedora kernel because
- we don't need all the latest cleverness in power saving - we need as many drivers for network and usb kit as possible - we don't have easy access to kernel folk - Deepak is kept busy with laptop concerns
I enabled the bonding module before I ran the sd_fixup script. At the end, it failed to do the chroot thing, so I looked at the chroot.sh script in /XO-alt-distro/distro/fedora-9 and then manually did:
sed -i "/VolGroup00/d" /media/disk/etc/fstab cp olpc.fth /media/disk/boot
Alternatively, you can use a more conventional disk partitioning scheme :-)
I don't have a USB to ethernet adaptor, so I downloaded and put the rpm in /root before I disconnected the 8 GB SD card. I booted up on an XO and did the usual XS stuff, including installing the rpm, and got what looked like a working XS, with the exception of failure to load the extra iptables modules. I booted up a regular XO, got an IP on msh0, and then successfully registered to the XSXO. Moodle looked like it was working on the XSXO, but when I go to http://schoolserver/moodle, all I get on the regular XO is a bunch of error messages related to scorm.
Overall, promising results :-) The iptables modules perhaps aren't included. That Moodle's failed is odd! /var/log/moodle/ will have an installation log that probably tells us what went wrong, can you post it.
I haven't tried ejabberd yet, though I suspect the little XSXO might be a little underpowered to handle that with too many users.
It should cope with 20~30 users. Simultaneous use with Moodle might need further tuning, but it can be made to work.
At any rate, this needs testing
definitely. But that's a great start :-)
associated with an XS, this might be a solution. Boa does work on a regular XO, but I don't know if that would work within a simple mesh environment.
We're still a bit tied to apache, can boa work with mod_python's low level hooks?
I bet this would even work on an XO with a broken screen if it was otherwise going to go unused, as you could either ssh in to do stuff or simply swap the SD card temporarily. Using ssh might be a better idea anyway, as the console display is very, very small.
Yeah. OTOH, I woudn't want to promote cannibalising the XS ;-) we'll see where this leads...
cheers,
