Mounted cifs shares, either manually or with /etc/fstab, are not visible as storage devices. They should show when browsing with Media Player or similar.
Q: How can I make the cifs shares visible as storage devices?
Note: I'm unable to use the great built-in gui for mounting as it adds the option "noatime" to the mount which makes timeshift malfunction (see first post in this thread). The default, when not specifying any mount option, is "relatime" which works like a charm. This is why I want to use fstab instead.
