Comment 3 for bug 1565882

Today it is possible to mount the SD card via the mount command. However, afaik to do so automatically one must manually change the root fs, which is discouraged.

I personally mount my SD card with ext4 fs using an edited /etc/rc.local and have not experienced any problems yet. However, I might not have realized them or they might appear with an touch update.

And not all apps support this manually mounted location, however I could convince the gallery app to show pictures using a symbolic link.

So to me the best solution seems to hope for a change in ciborium.
