mkext2.py does not handle block boundaries in directory contents correctly
When trying to run python, I found a bug in ext4fs and/or mkext2.py. With the python lib copied to the ramdisk, ext4fs fails to find
lib/python2.7/site.py in the directory (it does not show up in listing printed by ls and the python binary couldn't find it either). Trying to (re)create this empty file using edit causes an assertion to be hit:
Assertion failed (entry_len ⇐ block_size) in file "libext4_directory.c", line 354
site.py is an empty file. I was not able to reproduce this simply by adding an empty file to the root or a subdirectory of the ramdisk though.
I used amd64 build of HelenOS mainline,1792 with Zbigniew's python patches built using the old toolchain (GCC 4.7.2) (I suspect neither to be connected to this issue, though)
