So far all the contents are running well in the new system. I am facing a problem in auto-installing the contents from external hard-drive to the system. As similar to the earlier NEXS versions, I am trying to use the usbmount feature. While the script is running and the contents are being installed, 'systemd-udevd' genarates a timeout error (after 30 secs of the usb drive plugged in) and the process gets terminated. I find a timeout value to be 30 inside /sys/devices/pci:00/: 00:1d.0/usb2/2-1/2-1.3/2-1.3:1.0/host6/target6:0:0/6:0:0:0/. Therefore, I added a udev rule to change the timeout value of the device, but that didn't work. udev rule: 81-nexc.rules KERNEL==sdb, SUBSYSTEMS==scsi, DRIVERS==sd, ACTION==add, RUN+=/root/NEXC-timeout.sh NEXC-timeout.sh #!/bin/bash test=`echo $(udevadm info -q path -n /dev/sdb1) | sed 's/\/block\/sdb\/sdb1//g'` echo 120 /sys$test/timeout Next, I tried to modify the timeout value by adding following lines to /usr/share/usbmount/usbmount script right after mounting the external drive, but that doesn't seem to work either. echo 60 /sys$DEVPATH/../device/timeout The timeout values in both cases replace the respective default values, but has no effect in operation. What may be the possible ways of fixing this bug or working around the problem? Is there some other ways of auto-updating the contents from external hard-drive to the schoolserver in XSCE 5.0 ? Thanks in advance.

[Server-devel] iiab on xo-4
We switched xsce to using pip instead of rpms to install iiab in order to get the latest version. However, during the install process on an xo-4 I get IOError: [Errno 28] No space left on device.

Re: [Server-devel] [IIAB] iiab on xo-4
Hi Tim, pip builds its packages in /tmp by default. You can specify a different directory where you have enough disk space. See http://stackoverflow.com/questions/10617198/pip-creates-build-directories pip install -b customized_build_directory to specify another directory as build base directory, for example /tmp On Fri, Jul 25, 2014 at 2:20 PM, Tim Moody t...@timmoody.com wrote: We switched xsce to using pip instead of rpms to install iiab in order to get the latest version.

Re: [Server-devel] iiab on xo-4
On OLPC OS the /tmp directory is a tmpfs, with a limited size. See df /tmp Disabling that feature or changing the size is a step in my checklist before serious use of the OS as a server platform. But there will be other things to bite you later. It's not default Fedora. You could be using olpc-os-builder to make a build without optimisations for personal use and power management that we added. I agree with Braddock, tell pip to use another directory. -- James Cameron http://quozl.linux.org.au/ ___ Server-devel mailing list Server-devel@lists.laptop.org http://lists.laptop.org/listinfo/server-devel
