It's not different; it's identical. <http://www.ntfs.com/ntfs-sparse.htm>

The 'finger' command uses it too. In this day and age, that's generally seen
as a bad thing, though. :) And if the file isn't accessible (ie on fedora,
you're not running as root) it silently falls back to saying "never logged
in".

Suggestion: write this drop-in replacement (although ideally not in perl --
python is kinda the fedora-tools-language-of-choice) for the lastlog command
that does the same thing but uses the information from wtmp. Then, let's get
that into extras, and eventually have it replace the shadow-utils command. 

Code speaks louder than flamewars. :)
