pure-ftpd is now included in the standard repository packages, so one can just do a plain

To manually start the service, non-persistent:
 /sbin/service pure-ftpd start

 avahi-autoipd eth1

== Trackpad/Keyboard commands==
What kind of trackpad do I have?
 dmesg | grep psmouse<br />

XO 1.0 = 50<br />
<br />
Tap-to-click Persistent for older CL1/CL1A - edit the following file; to turn on set the param =1 or off =0
 /etc/modprobe.d/olpc.psmouse.conf

Tap-to-click Non-Persistent for newer CL1A - to turn ON

Tap-to-click Non-Persistent for newer CL1A - to turn OFF

== Adopt authority/permissions hint ==
add the NOPASSWD option in /etc/sudoers just for the scripts/commands you need 

== Sample yum syntax ==
For download only of yum updates to an External USB Volume PATRIOT with subdirectory called UpdateRpms
 yum update --downloadonly --nogpgcheck --downloaddir=/media/PATRIOT/UpdateRpms
For installing rpms from a USB volume PATRIOT with subdirectory called UpdateRpms and no internet access
 yum localinstall --nogpgcheck --disablerepo=* /media/PATRIOT/UpdateRpms/*.rpm

== Install bad and ugly gstreamer files to USB ==
For download only of rpm's to an External USB Volume PATRIOT with subdirectory called Guvcview.  This
will alter the repos used for subsequent Updates, so delete rpmfusion repos later if you wish

 http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-stable.noarch.rpm
