[CentOS] question on initrd.img file from images/pxeboot

[SilverTip257]

Just grab the xz package.

I roll initrds (for a custom pxe boot setup) on a CentOS 5.8 host.
I've rerolled the initrd for 6.2 some time ago and you've reminded me
to take care of 6.3 today.

Name       : xz
Arch       : x86_64
Version    : 4.999.9
Release    : 0.3.beta.20091007git.el5
Size       : 473 k
Repo       : installed
Summary    : LZMA compression utilities
URL        : http://tukaani.org/xz/
License    : LGPLv2+
Description: XZ Utils are an attempt to make LZMA compression easy to
use on free (as in
           : freedom) operating systems. This is achieved by providing
tools and libraries
           : which are similar to use than the equivalents of the most
popular existing
           : compression algorithms.
           :
           : LZMA is a general purpose compression algorithm designed
by Igor Pavlov as
           : part of 7-Zip. It provides high compression ratio while keeping the
           : decompression speed fast.
