Linux The tools used to boot Linux are changing. Specifically, the Grand Unified Bootloader is now officially in maintenance mode only, and GRUB's developers have abandoned the original GRUB in favor of an entirely rewritten package, known as GRUB 2. Discover GRUB 2's new capabilities and how to use it.

I last tested grub2 long -long- ago, so I can't really comment on how stable it is now.

However, it's not that people are lazy; The main problem with boot managers that if they break -nothing- works. You can't switch to last good known kernel / glibc, you're simply doomed.

As for your configuration, I have a far more complex setups (ranging from 3 x 320GB SATA drives to 16 x 144GB SAS drives), all running software RAID5 or RAID6.
In-order to solve the grub-doesn't-support-RAID[0/5/6] I usually setup two RAID arrays:
/dev/md0: a 200MB RAID1 across all drives.
/dev/md1: the main RAID5/6 array.

If the boot drive dies, I simply switch the BIOS to the next one. (If I somehow failed to write update the drive's MBR, I simply pxeboot/LiveCD and fix the MBR)
