Linux /boot: Out of Disk Space While Installing Package kernel-2.6.32-131.2.1.el6.x86_64

in Categories last updated June 8, 2011

I‘m trying to install RHEL 6 kernel updates and patches using the yum command and getting the following error:

Transaction Check Error:
  installing package kernel-2.6.32-131.2.1.el6.x86_64 needs 8MB on the /boot filesystem

Error Summary
-------------
Disk Requirements:
  At least 8MB more space needed on the /boot filesystem.

How do I fix this error and install RHEL kernel without increasing /boot size or reinstalling the operating system?

RHEL 6: semanage SELinux Command Not Found

in Categories last updated May 13, 2011

I‘m trying to use semanage command to configure certain elements of SELinux policy without requiring modification to or recompilation from policy sources under RHEL 6 server. But, I’m not able to find out this command and/or package name. How do I install semanage command under RedHat Enterprise Linux?
