BU Linux 6 (Neo) is a refresh of the BU Linux distribution that more closely aligns with RedHat Enterprise Linux 6.x / CentOS Linux 6.x. In previous releases of BU Linux we had rebuilt, repackaged, and in some cases made customizations to software as distributed by CentOS. This work was often time-intensive and also resulted in some package versions drifting from what was available in the standard CentOS distribution.
BU Linux 6 is constructed by taking the standard CentOS 6 and layering on configurations for DNS, Kerberos, NTP, Global UID, and other software that is specific to Boston University’s environment. We believe that this change in construction will make BU Linux closely match CentOS and RedHat Enterprise Linux, and will also allow IS&T to be more responsive when providing ongoing updates to software packages and Linux version upgrades.
- A new package, “bu-config”, now provides the BU specific configuration and modifications in a central place for a variety of CentOS configuration files.
- Neo will continue to have additional security enhancements
- Disallows null passwords
- Disables interactive initialization
- Requires a root password for entering system service mode
- Neo only customizes those packages that need BU modifications
- Reduces package version “drift” from standard CentOS
- Reduces time required to provide ongoing package updates and Linux version upgrades
- Includes the newer kernel so enhancements are automatically included
- Web distribution of the packages using an Apache server
- Majority of packages will be available directly from other repositories (CentOS, EPEL, RHEL, ATrpms, others)
- Many of the Monde packages are now provided by default from the EPEL software repository; others from ATrpms, NauLinux or RPMForge.
- The standard CentOS 6 distribution has SELinux enabled by default with targeted mode, so this will now be the default for BU Linux 6. SELinux was disabled in BU Linux 5 Monde.
- AFS is available, but is no longer installed by default.
- Due to the changing nature of the BU Linux 6 software distribution, systems should reinstalled as a fresh install rather than upgraded in place. As always, it is a good practice to routinely back up your systems, especially before reinstalling an operating system.
- The CentOS 6 packages installed by default for various installation types such as Desktop or Minimal differ from the default set of packages installed by BU Linux 5 Monde. This software can easily be installed with “yum” if it is required.
- The autoupdate utility by default only updates packages in the CentOS, EPEL, and BU Linux repositories. If you need rpms from other repositories to be automatically updated, these repositories should be listed in /etc/sysconfig/autoupdate
- Some software that was provided as part of the BU Linux 5 Monde distribution repository should now be retrieved from one of the ATrpms, NauLinux or RPMForge repositories (packages detailed in the last section of this page).
- Computer lab managers should be aware that the standard CentOS 6 by default does not disable interactive start-up, nor password protect the boot environment. These customizations will need to be made if they are required for lab use.
