Introduction
4 RedHawk Linux Version 5.4 Release Notes
1.4 System Updates
As RedHawk Linux updates are issued, they are made available for downloading from
Concurrent’s Software Portal.
NOTE
Concurrent does not recommend downloading Red Hat updates.
The RedHawk Linux kernel replaces the standard Red Hat kernel and is likely
to work with any version of the Red Hat distribution. However, installing
upgrades, especially to gcc and glibc, from sources other than Concurrent may
destabilize the system and is not recommended. Security updates from outside
sources may be installed if desired.
Instructions for downloading updates from the website are provided in the section “Software
Updates” on page 83.
