The Cache Manager stores the system type name of the local client machine in kernel memory. It reads in the default value from a hardcoded definition in the AFS client software.
The Cache Manager uses the system name as a substitute for the @sys variable in AFS pathnames. The variable is useful when creating a symbolic link from the local disk to an AFS directory that houses binaries for the client machine's system type. Because the @sys variable automatically steers the Cache Manager to the appropriate directory, you can create the same symbolic link on client machines of different system types. The link also remains valid when you upgrade the machine to a new system type.
Configuration is simplest if you use the system type names that AFS assigns. For a list, see the OpenAFS Release Notes.
To display the system name stored in kernel memory, use the sys or fs sysname command. To change the name, add the latter command's -newsys argument.
Issue the fs sysname or sys command.
% fs sysname % sys
The output of the fs sysname command has the following format:
Current sysname is 'system_name'
The sys command displays the system_name string with no other text.
Become the local superuser root on the machine, if you are not already, by issuing the su command.
% su root Password: <
Issue the fs sysname command, using the -newsys argument to specify the new name.
# fs sysname <
Is the shortest acceptable abbreviation of sysname.
Specifies the new system type name.
