Hello. I currently have an ext4 and ntfs partition on a usb 3.0 flash drive plugged into my Asus TM-AC1900 and I had noticed that the /opt directory is, while there, is not accessible. I had tried to remedy this by reinstalling entware using entware-setup.sh but it occurred again. I do notice a number of folders named "entware-old_2016-04-22_00-38" or similarly and am wondering if there's something I need to do after running the setup script, because I haven't and assumed that the script sets everything up with regards to entware being available per boot. I can still run opkg however. Thank you.
