All the +changes which have been gathered in the overlay archive are merged into the new +'system.sqf', thus (potentially) reducing the space requirements considerably. The +directory for the storage of these new archives must be passed as argument to the +script. +</p> + +<p>No further handling of these new archives is provided with <em>larch</em> +at present, for the simple reason that it is difficult to find a general solution to the +question of what to do with them. They cannot just replace the archives on the +boot medium because these are required to keep the <em>live</em> system running. +So some temporary storage is needed for them, and it is quite conceivable that there +is not enough space on the medium (as that might well be the reason for wanting +to recompress the system in the first place). +</p> + +<p>Thus some details of how to implement this rebuild feature are currently left to +the creativity of the user. I would, however suggest that the medium file 'larch/boot-init' +(see <a href="larch_sessionsave.html#boot-init">boot-init</a>) might be a useful place +to perform the replacement of the archives. You would just have to write a script +using 'larch-rebuild' to save the new archives somewhere, and write this 'boot-init' +script to replace the old ones with the new ones, remembering to also delete any +sqf files ending in '_' and '~' and the 'overlay.tar.lzo' archive. +</p> + +</div> + + + <div class="topref"><a href="#top">Top</a></div> + </div> + <!-- begin: #footer --> + <div id="footer"> + <div id="footer-content" role="contentinfo">© 2010 Michael Towers<br /> + Page layout assisted by <a href="http://www.yaml.de/">YAML</a> and + <a href="http://www.kuwata-lab.com/tenjin/">pyTenjin</a> + </div> + </div> + <!-- end: #footer --> + </div> + <!-- end: #col1 --> + <div id="bottom"><div id="bl"><div id="bm"></div></div></div> + </div> +</div> +<!-- full skiplink functionality in webkit browsers --> +<script src="css/yaml/core/js/webkit-focusfix.js" type="text/javascript"></script> +</body> +</html> |
