[13:24] <user24> is it possible to disable the dhcp server in edubuntu since i already have a dhcp server running on the network ?
[13:37] <stgraber> user24: emptying /etc/ltsp/dhcpd.conf should do the trick
[15:38] <tedmasterweb> Question about LXC: can it be used as the source for thin/fat clients? In other words, can I configure a distro inside of LXC and then serve it to thin clients, or do I not understand what LXC is used for?
[15:53] <highvoltage> tedmasterweb: I think alkisg and stgraber talked about something like that
[15:55] <stgraber> tedmasterweb: yes you can do that, you'll need to create a new apparmor profile for it though (or wait until we have an update allowing for lxc.aa_profile = unconfined to work)
[15:55] <highvoltage> I think there's some services for the desktop that might not start in a container, but if those aren't a problem then there's no reason why it wouldn't work for an application server
[15:56] <stgraber> tedmasterweb: you'll probably want an apparmor profile based on the default one but adding "mount -> /opt/ltsp/**," which allows for mounts to happen in the container chroot, otherwise creating/entering the chroot will be denied by apparmor
[15:57] <stgraber> tedmasterweb: you can either add that line to /etc/apparmor.d/lxc/lxc-default and run "sudo /etc/init.d/apparmor reload" or copy lxc-default to lxc-with-ltsp, rename the profile (first line of the file) and add the entry there. Then reload apparmor and set lxc.aa_profile = lxc-container-with-ltsp (or whatever profile name you choose)
[15:58] <stgraber> tedmasterweb: http://www.stgraber.org/2012/05/04/lxc-in-ubuntu-12-04-lts/ <- the nesting example there, uses lxc.aa_profile and can probably be used as an example of what you want to do
[15:58]  * highvoltage would rather keep the ltsp chroot on the server and have the desktop sessions in containers
[16:00] <tedmasterweb> These are fascinating answers and I'll do my best to process them. I'm on the verge of setting up an LTSP classroom for testing purposes and exploring the possibilities
[16:02] <tedmasterweb> I've found several resources on setting up LTSP but I'm still searching for the needle in the haystack: a tutorial, start to finish, on how to set up an LTSP classroom for K-12 (in other words, users that won't log in and shouldn't be able to modify their environment and users that will need their own accounts and some ability to configure their environment)
[16:04] <stgraber> highvoltage: right, that setup should work without any tweaks to the apparmor profile. Only corner case you might hit is fuse filesystems as provided by gvfs, I'm not sure we allow these, but that's an easy fix in the apparmor profile.
[21:29] <highvoltage> stgraber: could you review http://edubuntu.org/2012-05-05/edubuntu-at-uds ?
[21:32] <stgraber> highvoltage: looks good
