RHEL7 XFS Is A Step Backwards Forensically

Red Hat changed the default filesystem in Red Hat Enterprise Linux 7 (RHEL 7) to XFS. In RHEL 6, the default filesystem was EXT4. The rational for this change, according Denise Dumas, Director of Software Engineering for Red Hat was because “it is a better match for our enterprise customers”. I agree with this position, which incidentally is the position SUSE have maintained for a long time, except that forensically it is somewhat of a step backwards. You can examine a XFS file’s metadata using xfs_db but it is much easier to use the xfs_io utility. Just like xfs_db, xfs_io

Set up local RPM Installation Repository

There are a number of ways of installing additional RPM packages from installation media. However, if your network is fast and you are installing the same packages on a number of systems, it sometimes is easier to set up a simple local package repository and use yum to install the packages from there. This post shows you how to do this. Copy the new packages, or even the contents of an entire distribution to a suitable subdirectory on a local webserver.
