Hi, I am quite familiar with linux and somewhat familiar with the nvram shell command. I really appreciate that firmwares are being updated so regularly (such as Shibby's), and clearly, OpenSSL bugs etc. mandate that we regularly apply these updates. However, manually reconfiguring the firmware after each upgrade is a huge pain. I understand that backing up the complete NVRAM is not possible (why that is, I am not so sure). However, could it not be possible to backup some of the settings, like Wi-Fi keys, MAC addresses and so on? Is there a list of settings that one can safely export, keep and re-import after upgrading? What would I need to check if I wanted to manually find out which settings I could keep? Should I compare the NVRAM contents of the old and the new firmware versions (after resetting the NVRAM in each), and if an entry matches, would it be safe to copy over this particular setting? Some more questions for my understanding: - Does the order of entries in the NVRAM matter? - Do additional entries in the NVRAM hurt? Let's say I want to use this to send a message to the NSA in case they want my router, could I store an extra entry in the NVRAM with a greeting or would this mess up the other entries? Thanks!
