- Discussion about UnionFS from #rockbox-community
- 07:52 <JdGordon|> GodEater: dont say other filesystems are nodo :( ... i do sort of want to get NFS going on the mini2440 :p
- 07:52 <JdGordon|> which of course requires me to get around to installing rockbox on it
- 07:52 <GodEater> JdGordon|: well, they are
- 07:52 <GodEater> that being said, I do quite like the idea of unionfs
- 07:53 <GodEater> I'm not a fan of the <microsd1> thing
- 07:53 <JdGordon|> nothing except hardware related stuff is ever a real NoDo :D
- 07:53 <JdGordon|> it could actually be really simple to implement
- 07:53 <GodEater> the big problem I see with other filesystem support is windows users
- 07:54 <GodEater> a lot of whom would likely guy "huh? What's a filesystem?"
- 07:54 <JdGordon|> how does unionfs do file writing?
- 07:55 <GodEater> no idea - read the code :)
- 07:57 * JdGordon| suspects adding read support could be as simple as adding a few lines of code
- 07:57 <JdGordon|> hmm... should even be able to en/disable it on the fly
- 07:58 <JdGordon|> dircache would probably not play nice though
- 07:59 <GodEater> according to http://www.evolware.org/chri/hopeless.html there's a concept of "priority" with the filesystems you mount
- 07:59 <GodEater> so I guess writes go to the one with the highest priority
- 07:59 <GodEater> I imagine we could make this work once Rockbox does MTP properly
- 08:00 <GodEater> then the host support of the filesystem becomes a non issues.
- 08:00 <GodEater> but it does mean it'd only work on players where we have our own USB stack
- 08:01 <JdGordon|> na, once its connected to usb its not rockbox's problem anymore
- 08:02 <GodEater> that's true only if you're using UMS
- 08:03 <GodEater> yay, package state has finally changed to "with delivery courier"
- 08:03 <GodEater> JdGordon|: I found this too : http://www.linuxjournal.com/article/7714
- 08:05 <JdGordon|> too long to read at this time of night :)
- 08:05 <JdGordon|> umm... morning :p
- 08:06 <JdGordon|> we could stick a <unionFS> "mount point" in the / directory
- 08:06 <JdGordon|> which is read only
- 08:08 <JdGordon|> this could have some serious fun stuff.... if the SD card has priority you could setup the .rockbox folder on the internal storage with no settings at all, so if oyu boot with no card you get default everything
- 08:09 * JdGordon| hates it when fun ideas show up after bed time
- 08:09 <pixelma> what about same named files (in same named subfolders) on the card and on the internal memory? Although this discussion might be better suited for the main chan
- 08:10 <JdGordon|> im not in main chan :p
- 08:10 >>>> petur (n=petur@rockbox/developer/petur) has joined #rockbox-community
- 08:10 <GodEater> pixelma: that's where the priority thing comes in
- 08:10 <JdGordon|> very simple precendance... if /music/a.file is in internal storage (or whichever has higher priority) it doesnt try the other
- 08:10 <GodEater> if you have the same file in two matching places, the higher priority one is used
- 08:11 <pixelma> he could simply use the database (if he's talking audio files)
- 08:11 <JdGordon|> same file NAME... not file
- 08:11 <GodEater> pixelma: he could, but he specifically mentions he doesn't rely on tagging
