livesys - Reports the configured CPU/operating system type
The livesys command displays the string stored in kernel memory that indicates the local machine's CPU/operating system (OS) type, conventionally called the sysname. The Cache Manager substitutes this string for the @sys variable which can occur in AFS pathnames; the OpenAFS Quick Start Guides and OpenAFS Administration Guide explain how using @sys can simplify cell configuration.
To set a new value in kernel memory, use the fs sysname command, which can also be used to view the current value. If a sysname list was set using fs sysname, only the first value in the list will be reported by livesys.
To see the full sysname list, use fs sysname rather than this command. livesys is mostly useful for scripts that need to know the primary sysname for the local system (to create directories that will later be addressed using @sys, for example).
livesys first appeared in OpenAFS 1.2.2. Scripts that need to support older versions of AFS should parse the output of fs sysname or use sys.
The machine's system type appears as a text string:
The following example shows the output produced on a Linux system with a 2.6 kernel:
% livesys i386_linux26
