/boot can be loaded or and I like to have a resuce image on there just
incase I stuff something up on /, for the cost of a 1 partition and a
separate /boot it feel a bit better, when its part of / anything can
happen to it

I have had to recover to many servers and I like having root on a non
lvm partition just another layer I don't need it there is a problem.
Data is different.
So I can have a fully functional machine, or there could be something
wrong with the machine but I can boot into root, or the next stage
is being able to boot into the rescue image on /boot.
raid1 is easy to deal with when thing go wrong and again the cost of it
is minimal 1 partition slot and managing your data needs
