Re: stat to open race condition (was Re: [Integrit-users] Re: integrit)

Probably, the only reason i said its not SO important is that if the file
that its link to changes, itll still report an error. at most youre
wasting the time to read the file to make the checksum.  Other than that,
your program will basically work the same, because if youre statting  the
destination of the link, youll know if hte link has changed. make sense?

btw, i forgot to say, this project kicks ass. rock on.
