A quick question -- I want to upgrade the firmware on my DuoV2 to 5.3.8 (from 5.3.8) -- will it wipe out my custom changes on the box? I have e.g added backports/contrib/non-free to my apt sources list and installed some other things using easy_install. I have also changed DNS, smb etc configs a bit.
Some of those changes may be lost especially if you didn't follow the conventions used by the ReadyNAS. If you think it might be a good idea to rearrange where config files are located (or something like that) it isn't.
However adding new files should be fine.
I you simply reboot the ReadyNAS are any of the changes lost? If so you probably need to write them to the sqlite3 database.
A firmware update will overwrite a number of files so you should make a note of your custom changes before doing the update just in case.
All changes I did are persistent across reboots. And I followed Debian conventions (I don't think I know what ReadNAS conventions are) when doing custom changes. So there are some config filed changed under /etc/, some users added. That is pretty much it.
