In Marshmallow (and consequently in CM13), the external SD card is mounted at a path that contains its serial number. I have a bunch of Tasker tasks, the occasional script, and lots and lots of apps configured with a specific path to the external SD card (in my case, /external_sd because that's where it was in CM12).
Is there anything sensible I can do about this change in Marshmallow? Fixing paths everywhere just because I've upgraded to a faster/larger SD card (which has a different serial number) is not going to be fun.
How would I go about making the external SD card available under "/external_sd" on CM13/Marshmallow?
