Let me take a step down in tone.  It is not my intention to attack the
work you are doing.  In general, I believe you know what you are
talking about, are making the correct decisions and are working in the
right direction.

Good point.  Let me retreat and suggest that changing DEV_BSIZE
is a difficult goal.  I am looking forward to it being successfully
accomplished.

Good.  This is mostly what I was getting at.

I am hearing you say that when you are done, I will be able to take a
disk with 2k sectors that has a filesystem that was created on NetBSD
1.5 with DEV_BSIZE=2048, dd it onto a disk that has 1k sectors and
then mount it on my system compiled with DEV_BSIZE=512.

This will make me happy.

| Uhm, that's why I wanted to see an inode. :-)

Ok, I have a UFS filesystem image from a NeXT 1k scsi disk as well
as the UFS filesystem image from the NeXTstep 3.3 install CD (2k media)
If there is a particular analysis you would like, please let me know.
I will examine the inode again and let you know what I see.  I hope to
have the time this weekend or over the upcoming holiday.

These were my requirements, please do not consider them imposed on you.

Thanks,
