Cannot set time of file with touch command

$ touch file1.txt
touch: setting times of `file1.txt': Function not implemented
$ ls -l
-rw-r--r-- 1 packard packard 0 Dec 31 1969 file1.txt

can't recover file after mount

hi all
After mounting the correct png image, the mounted folder contains a file that differs from the original one. I have tested much time and in I have got a new file in each stage.
My OS is Debian testing.

Directory Support

There is no support for storing items in directories 👎

Application crashes with segfault when mounting the drive.

The application has a bug in https://github.com/mgeitz/albumfs/blob/master/afs.c#L562 where strlen is called instead of sizeof on a freshly allocated memory. As a result the tmp buffer size is random, and any operations on it (like memset, which in turn uses correctly sizeof) can smash the stack and cause the application to crash.

Cannot write into file with echo or nano

$ echo "Hi there" > file1.txt
bash: file1.txt: Function not implemented

The message "[ Error writing file1.txt: Function not implemented ]" is show in Nano when attempting to write the file contents to disk.

Segmentation Fault when formatting new drive with only 2 PNGs

This is a case where the user is informed that they do not have enough valid PNGs (minimum 2, but that includes a root, right?), and if the user does not have enough, the application does a segmentation fault. see the logs below:

[josh@localhost ~]$ albumfs -format Background.png
Enter drive name:
stuff
Enter encryption key for stuff.afs:
qwerasdf
Not enough images in /home/josh/ to create stuff.afs. At least 2 valid PNG images required.
Current valid images:
