I am using “new” Foris/Storage plugin (my /srv directory is on a usb flash drive now), but I discovered that the internal drive /dev/mmcblk0p1 is mounted to /tmp/old-srv (together with /). What is it for?
In the /tmp/old-srv/srv directory are some leftovers from original /srv, it seems like there is only a directory structure there without any files.
