Hi Narendra, if I understand correctly you are using Sugar on Fedora and not an OLPC build. The olpc-update command is meant to update olpc-images for the XO. For updating your configuration you need to use the distribution specific means. Fedora 12 has Sugar 0.86.x which as actually a newer version than what you would get in http://build.laptop.org/10.2.0/os206/ which is Sugar 0.84.x. I guess F12 is the latest arm version you get for Fedora [1]. Otherwise Sugar 0.88 is packaged in Fedora 13 and 0.90 is in F14.

Paul, what do you think about powerd implementing org.freedesktop.UPower ? http://upower.freedesktop.org/docs/UPower.html If so, Lennart could be interested in accepting a patch that makes Avahi listen for Resuming() and that implements the wake-up behavior as specified in http://files.multicastdns.org/draft-cheshire-dnsext-multicastdns.txt . Thanks for that pointer and contacting Lennart. The funny part is: the draft expired yesterday :) After a quick read, looks like it would involve querying the network with the QU bit set so the other nodes can send unicast replies instead of multicast, thus saving bandwidth. Yes the draft talks in section 5.5 Questions Requesting Unicast Responses the case when using unicast responses instead of multicast responses in the resume case. The document states that after the first query multicast responses should be used. Appendix D contains some interesting points why using multicast responses is not inefficient.

We should probably have olpc-update check /etc/redhat-release for the string 'OLPC release' and bail out if it isn't found with a message like 'This is not an official OLPC release, cannot update. Please use your distributions package manager'. This should allow the utility to live in a distro's eco-system but not cause complete confusion if it is installed and run on non-OLPC builds. -Jon ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
