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

[Andrew Reis]

If you're updating your CentOS 5.X installation regularly at all, xz
and xz-libs should be automatically downloaded as a dependency for
something, can't quite remember what. Most of our 5.X machines have
pulled it when updates are run weekly.

not the PXE one. If I do "file initrd.img" it just says data.
