title: redhawk install process modifies /dev/* to usrp:usrp
body: <p>I recently installed redhawk on RHEL 5.8 using the instructions found here <a href="http://redhawksdr.github.io/Documentation/mainch2.html#x4-60002" rel="nofollow">http://redhawksdr.github.io/Documentation/mainch2.html#x4-60002</a></p>
  
  <p>I was installing from the redhawk-yum-1.10.0-10-el5-x86_64.tar.gz  file.</p>
  
  <p>After the installation and a reboot I found that all the files in /dev/ on the system had been changed to be owned by usrp:usrp and permissions were changed so that other users could not write to those files.
  This created a lot of problems as many user scripts on the system write things to /dev/null which became unavailable.</p>
  
  <p>Has anyone seen this before?</p>
  
  <p>I also noticed that all the directories like /usr/local/redhawk were owned by root:root instead of redhawk:redhawk.</p>
  
  <p>UPDATE: 
  I found that even after restoring the correct ownership and permissions to /dev/* files a reboot reverted those changes. Then I removed the file <code>/etc/udev/rules.d/10-usrp-udh.rules</code> and restored the correct permissions once more. After a reboot this time, the correct permissions persisted and the problem ended. Something must be up with the USRP-UDH rules installed by the UDH RPM with redhawk in EL5 series installer.</p>
