Discussion on fedora-devel on very slow writing to the device when large files are written in short writes. Maybe the kernel isn't buffering all the writes together, for whatever reason. ISTR that we've seen some large-file-writing issues on our side as well -- some related to the SD card

dbus session in VT / ssh sessions

2009-11-11 Thread Martin Langhoff
On build 802, we had some tricks to make dbus connections work transparently to the dbus session of the 'olpc' user. Does anybody remember what those tricks are? What package or build script applies them, so we can hunt them down and consider inclusion in the F11 builds? Some of the fallout

manual SD OS install not working / hal crashing on boot

Re: manual SD OS install not working / hal crashing on boot

2009-11-11 Thread Richard A. Smith
This was because HAL was failing to start on boot, so X couldn't figure out any information about input devices. Yes. That was the exact symptom. HAL was failing to start due to bad permissions on /var/cache/hald (hal runs as the haldaemon user, not root). Why were these permissions
