Hi All, I am trying to recompile the stock kernel to include XFS. At install time of the OS I select to install the kernel source code however I do not have a /usr/src/linux-2.6.9-5.0.3.EL-smp directory. I then learned you must run "yum install kernel-sourcecode" to properly install the source. When I run the command this is what happens ( see below) . The error I get is: warning: rpmts_HdrFromFdno: V3 DSA signature: NOKEY, key ID 443e1821 public key not available for qt-devel-3.3.3-9.3.i386.rpm does anyone know what to do at this point? Thanks, Andrew [root at se1 kernels]# yum install kernel-sourcecode Setting up Install Process Setting up Repos update 100% |=========================| 951 B 00:00 base 100% |=========================| 1.1 kB 00:00 addons 100% |=========================| 951 B 00:00 extras 100% |=========================| 1.1 kB 00:00 Reading repository metadata in from local files update : ################################################## 109/109 base : ################################################## 1406/1406 extras : ################################################## 32/32 Parsing package install arguments Resolving Dependencies --> Populating transaction set with selected packages.
