Er who says that? It certainly isn't the case for LFS 1.1 (the only one I
know about). I believe XP uses LFS 1.1, too (as do NT4 and Win2k).
The easiest way to find out which version of LFS you are looking at is to
run ntfsdump_logfile /dev/partition | more or ntfsdump_logfile -f
ntfs_image_file | more. You need the more as the log record stuff is a
lot of bogus crap at the moment and it outputs tons of rubbish. But I
have been doing lots of work on the restart pages parts and what I say
there should be correct and the output from ntfsdump_logfile regarding the
restart pages should be correct, too.

Have you looked at the most recent include/ntfs/logfile.h? That contains
a lot of good info about the restart pages and how dirty/clean can be
distinguished. And that is I believe correct for LFS 1.1.
If you believe they are bogus then please let me know which bits and
why...
Best regards,
Anton
