How to Set the Value of a Kernel Parameter

1. Become root.

2. Edit the /etc/system file and add a line to set the parameter.

   Each entry should follow this form:

   set module:symbol=value

   where module is the name of the kernel module that contains the required parameter, symbol is the name of the parameter, and value is the numerical value to assign to the parameter. For example:

   set nfs:nfs_nra=4

   would change the number of read-ahead blocks that are read for file systems mounted using NFS version 2 software.

3. Reboot the system.
