For Linux, this is completely false.  You can use a RAID-1 for the root 
partition, or use a RAID-1 /boot partition, and a RAID-5 root 

Hardware raid only adds expense, bugs, slowness, and makes it harder to 
fix when the raid controller does something stupid.

I've never had Linux software raid do something that I couldn't recover 
the data from.  I've had hardware raids decide to eat volumes where I 
put in a disk that wasn't pristine, or decide to fail known-good disks, 
or decide to scramble the bits when upgrading the firmware.  Not fun.
