I just reset my Linksys router WRT32x recently. After reset, I noticed that there are 35 packages need to update under the "Software" "Update" page. As the router is reset and clean, is it possible the create one button "Update all" for update all packages in one click? This can help to make sure the reset router has the latest packages installed.
Based on the numerous problems upgrading packages has caused, Iād say no, this would not be added. You are feee to add a button that triggers a script to do this, but read this:
Upgrading packages (via the CLI opkg upgrade command or the LuCI Upgrade... button) can result in major problems. It is generally highly discouraged, unless you know what you are doing or if there is specific instruction to do so.
