If you have been doing custom kernel builds you will find old vmlinux-
<version> and initrd-<version>.img files in /boot.  Be sure to edit
/boot/grub/grub.conf to match what you clean up.

Old kernel sources are very large compared to the compiled kernels.


  rpm -e kernel-source-<version>

or for newer kernels:

  rpm -e kernel-sourcecode-<version>

If not installed by RPM, sources can be cleaned up while at a level
above the build directory by:

  rm -rf linux-<version>

For old update files - depending on update method:

  yum clean
  apt-get autoclean
  apt-get clean # more agressive

Seems like up2date should have a similar option but it's not obvious and
I don't use it.  Could do

  find /var/spool/up2date -type f -name "*.rpm" -exec /bin/rm {} \;

If you're desperate for space and feeling brave.

And leave you with an unbootable machine? ;^)
