Thank you for the tuning page!  I and, I fear, others made the mistake of 
assuming that because SOFTUPDATES is in the kernel that it is automatically 
enabled for the disks.  Nothing printed during boot leads me to believe 
otherwise and no mention was made of checking the flag using tunefs in 
/usr/src/UPDATING.  My drives formatted with standard methods in the past 
had soft updates disabled.

Perhaps there should be a message somewhere prominent encouraging people to 
check whether their drives really have soft updates enabled.  It would also 
be useful if something during boot showed whether a mount would be using 
soft updates.

-Michael
