Re: [cwelug] Has anyone tried the 200 line kernel patch alternative in Ubuntu?

Mr. Citek, This script is brillant.  Thank you.  It is brillant not only because you had the knowledge and ability to write it, but also and especially because you took the time to do and to share it. Mind if I forward your message to webupd8 ?  (removing e-mail addresses but leaving in your name for due attribution) It seems that the main point of contention in regard to this solution is that it is of no benefit at all for those who only use guis and never open terminals / command lines and that it only helps those who mix command line activity with gui windows and/or perform multiple command line tasks.  Would you agree with that assessment or would you say that it might even benefit those gui only users?

I'm not a big fan of the "edit this file and add this" instructions. So here it is in a single cut-n-paste script for those of you running Ubuntu: --- start cut here --- sudo true && ( # create bootup script { cat <<eof #!/bin/bash mkdir -p /dev/cgroup/cpu mount -t cgroup cgroup /dev/cgroup/cpu -o cpu mkdir -m 0777 /dev/cgroup/cpu/user echo "/usr/local/sbin/cgroup_clean" > /dev/cgroup/cpu/release_agent eof } | sudo tee -a /etc/init.d/cgroup sudo chmod +x /etc/init.d/cgroup sudo ln -snf ../init.d/cgroup /etc/rcS.d/S10cgroup # create initiate script { cat <<"eof" if [ "$PS1" ] ; then mkdir -p -m 0700 /dev/cgroup/cpu/user/$$ > /dev/null 2>&1 echo $$ > /dev/cgroup/cpu/user/$$/tasks echo "1" > /dev/cgroup/cpu/user/$$/notify_on_release fi eof } | sudo tee /etc/profile.d/cgroup.sh # create cleanup script { cat <<"eof" #!/bin/sh rmdir /dev/cgroup/cpu/$* eof } | sudo tee /usr/local/sbin/cgroup_clean sudo chmod +x /usr/local/sbin/cgroup_clean ) --- end cut here --- You can verify the files were created with these commands: # Verify ls -la \ /etc/rcS.d/S10cgroup \ /etc/init.d/cgroup \ /etc/profile.d/cgroup.sh \ /usr/local/sbin/cgroup_clean head -1000 \ /etc/rcS.d/S10cgroup \ /etc/init.d/cgroup \ /etc/profile.d/cgroup.sh \ /usr/local/sbin/cgroup_clean And if you don't like it, you can remove the files with this command: # To remove the above scripts and symlinks sudo rm \ /etc/rcS.d/S10cgroup \ /etc/init.d/cgroup \ /etc/profile.d/cgroup.sh \ /usr/local/sbin/cgroup_clean I'm running it on my UNR 10.04 eeePC network. Don't notice anything considerably different.
