134 Technical Product Specification
user and password - Optional argument that is the username and password for the FTP server.
Note: The -v argument can be up to 64 characters long.
The command returns a 0 if the update request is successful, and non-zero if an error occurs.
25.12 Hooks for User Scripts
The update process provides hooks for user scripts in two places during the update process. User
scripts should follow the convention of returning a "0" if successful and a non-zero for failure. The
user scripts will be invoked as a forked sub-shell.
25.12.1 Update Mode User Scripts
Entering update mode requires that all JFFS2 drives be unmounted, which requires that all
processes using these drives be stopped. Prior to entering update mode, the update process will call
user scripts located in /home/update/scripts/ if they exist. The update process will execute any
scripts that match the following pattern: /home/update/scripts/K*. No arguments are passed to
these scripts. The update process will not fail if a script returns a failure, however, the update
process will fail if the flash drives cannot be unmounted when necessary. A message indicating if
the script was successful or failed will be output to the terminal. See Section 25.6, “Update Mode”
on page 131 for more information on the Update Mode.
25.12.2 Data Restore User Scripts.
The update process will also execute user scripts following the update of the new /etc file system to
flash. The update process will execute any user scripts that match the following pattern:
/home/update/scripts/S*. Arguments will be passed that the scripts can use. These arguments are:
arg1 = Update Component Name: ["BlueCat", "etc_jffs", "RedBoot", "fpga"]
Note: For the user scripts, this argument will always be "etc_jffs".
arg2 = Update Direction: ["forward", "backward", "same"]
Note: "forward" means that the Update Package version is newer than the installed version. "same"
means they are the same, and "backward" means the Update Package version is older then the
installed version.
arg3 = Installed Package Version: i.e., "P00.105b". This is the version of the software that is
currently installed on the cmm.
arg4 = Update Package Version: i.e., "P00.111a". This is the version of the update package
software.
The update script will print a message to the terminal indicating whether the script was successful
or failed. Currently, the failure of one of these scripts does not cause the overall update process to
fail.
These scripts can be used to perform any user updates that need to coincide with the newly
installed version.
