+===== Zenteknix "FreeSlack Live" Modifications =====
+After installing slackware, and sanitizing it to FreeSlack, these steps can be used to convert the installation to an operationally "live" variant, which minimizes changes to disk during routine operation.
 ==== Migrate the ''/var'' footprint to a "live"-capable arrangement ====

+  * Create directory to house the memory-resident "live" portion of the ''/var'' footprint \\ ''mkdir /var/live''

+  * Initialize the "live" area: \\ ''mount -t tmpfs tmpfs /var/live -o nodev,uid=0,gid=0,size=100m''

   * Initialize the storage "layers" from the current "live" footprint
@@ Line 50: / Line 71: @@
 ==== Design and Prune the Storage Layers ====
   * The /usr/share/mime directory is re-built at every boot, so migrating that into the "live" footprint makes sense: \\ ''mkdir -p /var/static/usr /var/live/usr/share'' \\ ''chmod 755 /var/static/usr /var/live/usr /var/live/usr/share'' \\ ''cd /usr/share'' \\ ''mv mime /var/live/usr/share'' \\ ''ln -s /var/live/usr/share/mime'' \\ ''rsync -ai /var/live/usr/ /var/static/usr/''
-  * I have these links:
+  * The rationale behind the various things residing under the ''/var'' footprint can be a bit diverse, and there are some of these things that benefit from some persistence across a reboot.  To accommodate this (as well as minimize in-memory space occupied by the "live" footprint), one can migrate selected subdirectories from the directory tree under ''/var/live'', in a rather "surgical" fashion, to a location designated as the "persistent storage layer" (I chose ''/opt/sys/var''), and populate the ''/var/live'' tree with the symbolic links to the respective locations.  In doing this with a stock slackware installation, I start out with these links:<code>/var/live/log/setup               -> /opt/sys/var/log/setup
-    |/var/live/log/setup |  ->  |/opt/sys/var/log/setup  |

+  * After migrating subdirectories and populating the respective links under ''/var/live'', synchronizing to ''/var/static'' should be performed.  This can either be done manually by repeating the process under ''/var/static'', or it can be scripted, or (if no other undesired changes have occurred under ''/var/live''): \\ ''rsync -ai /var/live/ /var/static/''
