Would you be happy if the handbook section added a caution, or referred 
to the section that discusses the write cache?

(FWIW - I have seen Linux + ext3 systems destroyed by power failure 
because the admins refused to disable write caching on ATA drives - 
Neither journelling or softupdates is much help if the HW is kidding you 
about write acknowledgment).

Cheers
