That should have been written in docs several years ago :) .
We though we had full softupdates support and never looked at the
sources to confirm that.

Thanks a lot for the explanation.
Unfortunately, 5.x is not stable enough now for production use.
And  again,  there  is no guarantee that a panic will not occur before
the check is done.

Can  I  ask  you,  is  there  a filesystem that could be considered as
substitution of FFS in FreeBSD for better reliability and performance.
I mean in terms of compatibility and license.

BTW,  please fix a bug in dirpref(), it should use 64-bit counters. At
least, make sure it does not divide by zero. You can find the details
at http://lists.freebsd.org/pipermail/freebsd-stable/2004-August/008563.html
