Storing Scripts in Flash Memory

By default, scripts are stored in and executed from the /var/db/scripts/ directory on the device's hard drive under the subdirectory appropriate to the script type. To store scripts in and load them from flash memory instead, include the load-scripts-from-flash statement at the [edit system scripts] hierarchy level:

[edit]user@host# set system scripts load-scripts-from-flash

When you add the load-scripts-from-flash statement in the configuration, all commit, event, operation, and script library scripts are loaded from the /config/scripts/ directory on the flash drive under the subdirectory appropriate to the script type. You must manually move scripts from the hard drive to the flash drive. They are not moved automatically. Similarly, if you delete the load-scripts-from-flash statement from the configuration, you must manually copy the scripts from the flash drive to the hard drive to ensure that the current versions of the scripts are executed. Changing the scripts’ physical location has no effect on their operation.

The /var/run/scripts/ directory always links to the directory from which the scripts are loaded. If you do not set the load-scripts-from-flash statement in the configuration, /var/run/scripts/ points to the /var/db/scripts/ directory on the device’s hard drive. If you set the load-scripts-from-flash statement in the configuration, /var/run/scripts/ points to the /config/scripts/ directory in flash memory.

To view the scripts currently on the device, list the contents of /var/run/scripts/type/, where type is the subdirectory appropriate to the script type. In the following example, the load-scripts-from-flash statement is not configured. In this case, /var/run/scripts/commit/ points to the/var/db/scripts/commit/ directory on the hard drive. Listing the files for /var/run/scripts/commit/ is identical to listing the files in the /var/db/scripts/commit/ directory.

user@host>file list /var/run/scripts/commit

/var/run/scripts/commit:
commit-changes-load-replace.slax
commit-protect.slax
user@host> file list /var/db/scripts/commit

/var/db/scripts/commit:
commit-changes-load-replace.slax
commit-protect.slax
user@host> file list /config/scripts/commit
