I followed this tutorial to make the SD card of my pi read only. However when I plug in a USB drive stick, which is then auto mounted by the usbmount package as /media/usbX , the usb stick is also read only.
How do I get it to automount as read and write?
I guess it is read-only because it is mounted below / And / is readonly because /etc/fstab has:
proc /proc proc defaults 0 0
[...]
/dev/mmcblk0p2 / ext4 ro,noatime 0 1
[...]
