Tunable file-manipulation commands

The following commands normally manipulate files in the /etc/tunables directory, but the files can be located anywhere. Therefore, as long as the file name does not contain a forward slash (/), all the file names specified are expanded to /etc/tunables/filename.

To guarantee the consistency of their content, all the files are locked before any updates are made. The commands tunsave, tuncheck (only if successful), and tundefault -r all update the info stanza.
