The problems with softdeps, as I've experienced them, are that often  
you won't really know you have a problem until its too late (i.e.  
where restoring from backups is complicated by the fact you've got to  
go back several days and perhaps do several restores before finding  
clean data), or sometimes the simplest little system failure can  
quickly cascade into one requiring a full wreck and rebuild instead of  
a simple reboot.

I personally don't dare to use softdeps on any critical file system  
any more, even on systems with hardware RAID and a good UPS, etc.   
I'll only use it for the likes of /usr/pkg or /usr/obj, etc. where  
everything can be thrown away or replaced with minimal hassle.
