New
features in version 4 include:
Enhanced auditing framework Red Hat
Enterprise Linux 4 incorporates the new standard
auditing framework for Linux systems. This framework
offers flexibility so that system calls and their
arguments can be filtered by user, group, process and
device with a variety of options
Hardware support Red Hat Enterprise
Linux 4 includes a new Hardware Abstraction Layer that
provides robust plug-and-play hardware support
Virtual memory subsystem
Improvements in the virtual memory subsystem have been
incorporated to better address mission-critical
workloads with large memory configurations, such as
database deployments. Default parameters have been
refined so that virtual memory performance is more
deterministic as memory use increases. New features also
allow the kernel to map through data structures more
efficiently and reduce paging
Interoperability Red Hat Enterprise
Linux 4 includes Samba 3.0 for interoperability with
Windows file sharing and printing using the SMB/CIFS
standards. The GNOME desktop environment automatically
discovers available Windows file shares and print
services on the local area network.
