Why should this be placed in *kernel* documentation anyway? The "dangers 
of RAID", the hints that "backups are a good idea" - isn't that something 
for howtos for sysadmins? No end-user will ever look into Documentation/ 
anyway. The sysadmins should know what they're doing and see the upsides 
and downsides of RAID and journalling filesystems. And they'll turn to 
howtos and tutorials to find out. And maybe seek *reference* documentation 
in Documentation/ - but I don't think Storage-101 should be covered in 
a mostly hidden place like Documentation/.
