This is a modified version of a small script I've posted here. It may be useful when many sfs files are loaded. It prints the current aufs stack starting with the top most layer. The state of the stack is received from /sys/fs/aufs.
It's only been tested on my Fossapup64 9.5 pupmode 5, 12, 13 with a savefile (not tested with a save folder).
