ClearCase is dependent on the version of the kernel being used. IBM/Rational has information at their website indicating which OS/Kernel they support. Later versions of RHEL and SLES are on that list. I have never seen Fedora listed there. http://www-1.ibm.com/support/docview.wss?uid=swg21136950
If it runs on RHEL, you might try using CentOS instead of Fedora... Chris
