Hello,
How create memory disk from /etc/fstab in FreeBSD 6 without soft-updates?
As I can see it impossible.
flag -S not allowed in compatibility mode, but by default disk created
with soft-updates turned on.
I see to ways to fix this problem:
1. In compatibility mode turn off soft-updates

2. In compatibility mode allow -S option

P. S. Benchmark show that memory disk mounted in async mode work
up to 30% faster when soft-updates turned off
