I'm wondering if there is a way for me to maintain multiple distinct music libraries - each in its own directory and employing the database - on a single 5th, 6th, or 7th Gen iPod running Rockbox, and be able to switch back and forth between libraries at least somewhat readily without having to rebuild the database each time? Ideally, it would be great if I could somehow put the selection of a specific library 'above' a single unified database so that when I entered into the database menus I would see only the tracks from that selected library. I'm guessing that isn't possible given Rockbox's current architecture, and so my mind starts going somewhat "Rube Goldberg".
The only projected scheme I have come up with so far would be to install multiple ".rockbox" directories with only one actually named exactly ".rockbox" at any given time (of course). I would then initially have to progressively rename and boot into each of those installation directories and place the database.ignore files such that only one specific music library would be used for each installation's database build. After setting all of that up (only once in a very great while, I hope...) the question becomes how do I most easily rename the installation directories in order to reboot into the one I want? The only solution I have for that is to boot the iPod into Disk Mode, connect to a computer and rename the outgoing and incoming installation directories, and then reboot back into Rockbox. That is obviously a very awkward and inconvenient way to make the transition, and completely unfeasible while doing something like riding a bus.
I have a vague recollection of reading something somewhere about maintaining multiple Rockbox installations on a single device, but I can't find it.
Does anyone here have any suggestions for improvements to my harebrained scheme (including "give it up")?
After this topic I will try to go quiet for a while and give everyone (especially the developers) a break....
