Fixes #1710 What do you think? * It first uses `TEMP_DIR` (`/debug_ramdisk`) if it exists + is is empty. * Otherwise it tries to create a random directory in `/dev`. * If that fails, it goes through a list of directories (including `TEMP_DIR_LEGACY`), and chooses the first one that is empty. * If no empty directory it chooses the first one that exists --------- Co-authored-by: user <user@localhost>
