S2, writing rights on an external sdcard

Added by André Ockers 8 days ago

Dear reader,

After formatting a sdcard to ext4 and giving it a recognizable name, I inserted it into my S2 Replicant.
After some searching in file manager Amaze I found the sdcard under a very long set of characters under /storage.
I wasn't allowed to change this long folder name and I wasn't allowed to make a folder in it.
So how do I get writing rights on my sdcard?
