Typically, I have / on 2 small RAID1 partitions making the array on the
first
2 HDD (1 or 2 gigs), and /usr on a LVM on a much, much larger RAID array
(I use mostly software RAID1 and RAID10, but in some cases, much bigger
hardware RAID5). So yes, that's my usual server setup.

Also, / is a partition on which almost nothing is read or written, while
the others (eg: /usr, /var, /tmp, swap) are a lot more I/O intensive.
Which means that / is less prone to failure. Often, the 2nd RAID
array gets degraded, but / isn't. So it does make a lot of sense to
setup things this way, and yes, / is less prone to HD crashes this
way (I'm talking from 10 years of experience running about 100
servers this way, so it's not just theory, it's very practical experience).

It does add value, as per above.

I'll keep in mind Marco's suggestion of grml-rescueboot which I didn't
know and try in the next following days, it looks cool!
