Startup

During system startup the virtual file system is populated with a '/local' directory that contains symbolic links to directories with the '/system/mounts/TEMP' directory, which has a /tmpfs/ filesystem mounted to it.

During system startup the /system/mounts/TEMP' directory is populated with a copy of the directories that are contained within the '/system/defaults/' directory.

Directory Target Copied from
/local/data /system/mounts/TEMP/data /system/defaults/data
/local/log /system/mounts/TEMP/log /system/defaults/log
/local/settings /system/mounts/TEMP/settings /system/defaults/settings
/local/users /system/mounts/TEMP/users /system/defaults/users

During the system build the '/system/mounts/TEMP' directory contains symbolic links pointing to the directories under the '/system/defaults' directory so that these can be populated with any required build scripts.
